Morning review · 15 October, 06:00 Israel time
The scheduled morning check ran successfully. The outlook for the coming week is broadly unchanged, with wind and possible dust today the main immediate watch point. Yesterday’s heat warning has expired. The dedicated Midburn window below covers 28 October–7 November: Camp set-ups + event.
Official warnings and nearby conditions
The IMS warning feed, checked at 06:00, contains no current warning polygon covering this pin. The previous heat-stress warning ended on 14 October at 20:00. New mountain-obscuration and western Negev low-cloud notices run until 07:00 today, but their polygons exclude the pin. Southern flood and storm feeds contain no notices. This is a time-limited feed check, not an assurance that conditions are safe.
At 05:00, Hazeva measured sustained wind of 24.1 km/h and a strongest gust in the preceding hour of 40.0 km/h, compared with 8.3 and 16.6 km/h in yesterday’s nearby-station snapshot. Hazeva is 17.8 km away and at a different elevation; these are not measurements at the camp. All four nearby stations report 0 mm in the past 24 hours. The 04:25 IMS national bulletin expects winds to strengthen today, with possible haze or dust mainly in southern and central Israel.
Temperatures, rain and wind for the next week
For 15–21 October, main daily high estimates are 26.7–29.1°C, with overnight lows 17.5–21.3°C. Today is about 29°C by day and 21°C at night. Compared with yesterday’s forecasts for the same dates, changes remain under 1°C for day/night temperatures and under 4.1 km/h for the main daily gust estimates.
Each day’s share of scenarios with at least 1 mm of rain is 0–2.54%, and the main daily rain amount remains 0 mm. These are model scenario shares, not calibrated real-world probabilities, and zero does not rule rain out. One GEM forecast has a small 0.2 mm hourly rain signal today around 16:00. The latest radar frame, valid 05:50, shows no echo within roughly 20 km of the pin, with tiny returns roughly 35 km northeast. Fresh ICON/COSMO maps from 14 October 12 UTC leave the pin and nearby western highlands unshaded through Sunday morning. Complete upstream catchments have not been assessed, so this does not rule out a flash flood.
Main estimates for the strongest gust each day are 26–34 km/h. The clearest remaining threshold event in the next 72 hours is a single ICON forecast of 40.3 km/h at 20:00 on Friday, 16 October, up from 39.6 km/h in yesterday’s daily estimate. Gusts are brief stronger winds. The GFS daily maximum of 42.1 km/h for today includes a peak before this report, so it is not presented as a future 72-hour event. Later, the ICON 19 October outlier has eased from 49.7 to 40.3 km/h; GFS now reaches 30.2 km/h sustained wind that day. These individual forecasts are watch points, not a consensus or a structural safety rating.
Midburn · Camp set-ups + event · 28 October–7 November
Forecast confidence remains low. Across complete scenarios covering all eleven days, the period-average daily high is 26.1°C and average overnight low 16.8°C. The middle 80% of scenarios spans 24.1–28.9°C for that average high and 14.7–19.6°C for that average low. These are averages over the period, not limits on the temperature of an individual day.
Rain on at least one day, with a daily total of 1 mm or more: about 56% of scenarios, compared with about 60% yesterday. The total rain estimate for the whole period is 1.8 mm, with a middle-80% range of 0–13.2 mm. At least one gust reaching 40 km/h: about 23% of scenarios, compared with about 29% yesterday. The period’s peak-gust estimate is 32.4 km/h, with a 26.6–43.2 km/h middle-80% range. Both percentages are marked as mixed model signals, separately from the low confidence in this long-range outlook.
Rain and temperature use 52 complete members from two model families, NOAA and ECCC. Gusts use only 31 NOAA members; missing gusts from other sources are not treated as calm. Each member is followed through the entire period, and model families get equal weight. Daily probabilities are not averaged or assumed independent. These small changes do not establish a new event-weather pattern, and precise rain or wind timing is not reliable yet.
Longer-range cross-check and source coverage
The freshly reviewed ECMWF extended chart is a new 14 October 00 UTC cycle, retrieved at 06:01 today. Its weekly temperature picture remains slightly cooler than model normal for 19–25 October, then modestly warmer for 26 October–1 November and 2–8 November, with broad uncertainty. The late-October rain distribution includes a more extreme wet member than yesterday, while the median remains near the model-climate reference. That is not evidence of a broadly wetter consensus, a rain probability, or a specific wet day. Near-normal rainfall anomaly does not mean zero rain.
All 18 configured products were retried; 15 passed the numerical-use checks. AIGEFS was excluded because its metadata initialization is about 45 hours old. Both ACCESS requests still return no data. The archive retains these sources for follow-up; their absence is never filled with zero. There are 57 variable/date coverage changes, mostly from excluding AIGEFS and forecasts extending their horizons; these are not 57 weather changes. The only daily numeric change crossing the configured thresholds is the 29 October share for at least 0.2 mm falling 10.37 percentage points. At that lead time, it is a weak long-range detail. All 400 independent aggregation checks passed, including the 25-hour daylight-saving day.

What changed
57 date/variable combinations changed their available models or member counts; see the public data export. Such changes can shift a consensus without a forecast revision.
Daily outlook · detailed range
Bold is the family-balanced median; parentheses show the 10th–90th percentile model range. These are uncalibrated model estimates, not guaranteed limits. Rain probability refers to the whole local day; a model probability of 0% does not establish zero real-world risk.
Days 8–15 · lower confidence
Timing is increasingly uncertain. A narrower range or lower gust estimate can result from fewer available models, not improved certainty.
Later dates · period outlook only
Do not use these dates for precise rain timing or tent-loading decisions. Temperature ranges describe the period-average daily low/high across ensemble scenarios; rain is the period total. Wind/gust is the greatest modeled value anywhere in the period.
Wind and rain attention signals
Attention levels: sustained wind ≥30 km/h; gusts ≥40 km/h and ≥60 km/h. These are monitoring thresholds, not structural or equipment ratings. Individual models can show a useful warning signal even when the consensus is lower.

Official IMS check
Snapshot: 15 Oct 2026 06:00 IDT. Official warnings · National forecast
The exact coordinate falls in the IMS Northern Arava warning region. The Dimona forecast point is about 28 km north of the event site.
No warning in the fetched IMS list matched the site’s warning polygon.
At this snapshot, the southern flood and storm warning feeds contained no entries. This is a current check only; it does not rule out later warnings or upstream flash floods.
A separate notice for poor visibility in mountain cloud or mist includes the Negev Mountain region (15 Oct 2026 04:00 IDT–15 Oct 2026 07:00 IDT). Its polygon does not contain the event coordinate; routes through that region may differ.
A separate notice for a weather hazard includes the Negev Mountain region (15 Oct 2026 03:00 IDT–15 Oct 2026 07:00 IDT). Its polygon does not contain the event coordinate; routes through that region may differ.
Nearby measured conditions

Radar and regional rain maps
The IMS radar frame valid 15 October 05:50 IDT, about 11 minutes old at collection, shows no resolved precipitation echo at the pin or around the nearby Sede Boqer/Avdat highlands to its west. A georeferenced check found no colored echo within roughly 20 km of the pin. A few very small returns are visible farther north and northeast; the closest colored pixels in the nearby image window are approximately 35 km northeast. Their connection to the pin’s drainage has not been established. This describes radar echoes, not measured ground rainfall.
Fresh ICON-IL and COSMO-IL runs initialized 14 October 12Z were reviewed in 26 six-hour rainfall panels ending from 15 October 06Z to 18 October 06Z (09:00 IDT). Both leave the pin’s vicinity and the adjacent Negev highlands to its west unshaded. Rain is concentrated over the Mediterranean, northern Israel and the coast, at times reaching the southern coastal/northwestern Negev fringe on Friday and Saturday. The broad near-site rain picture remains similar to the previous review. These are new model runs, initialized 24 hours later than yesterday’s saved guidance: all 18 panels with overlapping valid times have changed image hashes, and eight panels add later valid times. Initialization was about 15 hours before this snapshot.
This qualitative map review does not delineate the complete upstream catchment or calculate runoff. Small rainfall features and terrain-related radar limitations can matter, so an unshaded forecast or absent echo is not an all-clear for flash flooding. The southern flood and storm feeds were successfully retrieved and contain no entries, but that result applies only to the 06:00 IDT check. Separately, the IMS national bulletin issued at 04:25 IDT says winds will strengthen today and haze or dust is possible mainly in southern and central Israel. That wind concern remains relevant even with little rain near the pin.

Extended outlook and historical context
ECMWF weekly guidance
Model initialized 2026-10-14T00:00:00Z; retrieved 2026-10-15T03:00:49.128264+00:00. Weekly anomalies are relative to ECMWF’s own model climate. They do not specify individual-day temperatures, rain timing or gusts.
Visually reviewed 15 October 2026: A new ECMWF cycle, initialized 14 October 00 UTC, retains a slight cool tilt for 19–25 October followed by a modest warm tilt for 26 October–1 November and 2–8 November. The ensemble spread is broad. Rainfall medians remain near the model-climate reference. The late-October upper extreme is wetter than in the previous cycle, but that does not establish a wetter consensus or specific rainy days. These are qualitative weekly signals, not daily forecasts.
Each box is labelled at the end of its weekly interval. In this run, 9 November represents 2–8 November, extending one day past this report’s 7 November endpoint. The graphic identifies the selected model grid point; it can differ from the requested coordinates. Model-climate anomalies must not be added mechanically to the ERA5 baseline below.

What the season has historically been like
Climate reference, not a 2026 forecast. ERA5 reanalysis for 1991–2020 at the requested location shows a substantial cooling tendency from mid-October into early November. These estimates represent a coarse model grid with elevation processing, rather than a weather station at the exact point.
1991–2020 calendar-period averages| Dates | Mean daily high | Mean daily low | Historical daily highs, 10th–90th percentile |
| 14–20 Oct | 31.0°C | 19.3°C | 27.3–35.1°C |
| 21–27 Oct | 29.6°C | 18.1°C | 26.2–33.5°C |
| 28 Oct–3 Nov | 27.3°C | 16.7°C | 24.4–30.5°C |
| 4–7 Nov | 26.4°C | 16.2°C | 22.8–30.6°C |
For the same 25 calendar days across those 30 years, total rain averaged 5.4 mm, with a median of 2.8 mm and a 10th–90th percentile range of 0.1–16.1 mm. At least one day with 1 mm or more occurred in 19 of 30 years. These historical frequencies are not the probability of rain this year. Local thunderstorms and runoff are poorly represented by a single coarse grid cell.
Historical daily maximum sustained model wind speed had a median of 12.7 km/h, with a 10th–90th percentile range of 8.5–17.3 km/h. These are background conditions, not current gust guidance; exposed ridges and channels can differ.

Latest metadata timestamps are provider status, not proof that every horizon belongs to that one run. Rolling forecast APIs can combine current short-range output with earlier long-range runs. In particular, extended GEM guidance can come from an earlier extended cycle. Raw responses and metadata are retained; exact fixed-run attribution is not asserted.
Sensitivity to including AI models
Repeating the calculation using only the physical ensembles (IFS, GEFS, ICON, GEM and MOGREPS), the largest difference over available days 1–15 is 1.8°C in the central high, 2.4°C in the central low, 2.5 percentage points in daily ≥1 mm rain probability, and 0.0 percentage points in ≥40 km/h gust probability. These are method-sensitivity checks, not proof that either blend is more accurate. Additional method details appear below.
Method and practical limits
- Each member is aggregated into local-day minima, maxima and rain totals before probabilities and quantiles are computed. Model variants share their family’s weight; available families receive equal weight. Deterministic forecasts are displayed separately.
- Temperature, rain, wind and gusts use their own available family sets. Models without gusts do not count as calm. A full day is required for a daily statistic; missing values are never converted to zero.
- These are family-balanced scenarios, not statistically independent votes. AI models, numerical models and national centers share data and sometimes initial conditions. In particular, Google WeatherNext 2 uses ECMWF initial conditions; Google is a model-family entry here, not an independent observational confirmation. A physical-model-only sensitivity comparison is provided. No local skill weighting or bias correction is claimed without adequate validation.
- Local dates follow Asia/Jerusalem, including the 25-hour day on 25 October. Hourly rain and gust intervals ending at midnight belong to the preceding day.
- Grid and interpolated point forecasts cannot resolve individual tents, gullies, exposed ridges or every convective shower. Nearby observations and official warnings supplement the models; they do not prove the weather at this exact pin.
- Daily CSV includes long-range numerical diagnostics for audit only; the main report intentionally summarizes dates beyond 15 days as periods.
