Area forecast discussion National Weather Service Pocatello Idaho 214 PM MDT sun Oct 4 2015 Discussion...Idaho sits in the col between an upper low in southeast Alberta and a deep upper low moving along the Southern California coast. May see isolated showers near the Wyoming border into this evening...but the rest of the area should remain dry. The California upper low is expected to move into southern Nevada Monday night...with isolated showers/thunderstorms spreading into the southern Highlands Monday afternoon. Precipitation increases in coverage in the southern Highlands Monday night...with an isolated shower possible in the central mountains precipitation expands northward into the eastern Highlands by Tuesday morning...continuing through the day until the upper low fills and drops south into Arizona Tuesday evening. Upper ridging builds up over the west on Wednesday resulting in dry and warmer conditions. GFS still tries to bring a minor wave over the top of the ridge into Idaho on Thursday...but only expect isolated showers in the central mountains and NE Highlands. The ridge reestablishes dominance Thursday night for dry and warm through Sunday morning. The ridge then breaks down to zonal flow...with the GFS bringing precipitation into the forecast area by Monday morning. The European model (ecmwf)...not so much. Will only go with isolated showers over the central mountains/NE Highlands Sun night...leaning toward the European model (ecmwf). Hedges && Aviation...northeast winds continue to diminish today with most 10 knots or less by early afternoon at byi...pih and Ida. Will have VFR conditions continue through Monday with light winds expected Monday. Gk && Fire weather...expect little significant through the next several days. Expect some isolated showers this evening and again Monday mainly in the southern Highlands. Will have a bit better chance for precipitation again mainly in the southern mountains Tuesday with a system passing to the south. May see some showers in northern mountains Thursday. General trend will be for warming and drying beyond Tuesday though. Gk && Pih watches/warnings/advisories... none. && $$
