ern Quebec this evening. Surface winds are taking a northeasterly component, and the earlier cu field around Staunton and Charlottesville is expanding into broken altostratus. Elsewhere, only a little cirrus is found, which will be the case until the lower cloud decks expand later tonight as the flow becomes easterly. In addition, the easterly flow may result in some spotty light rain or drizzle, mainly in the southern Shenandoah Valley and adjacent highlands. Lows tonight will be cooler than the last few nights, with readings in the 30s and 40s. Am not planning any major adjustments to temperatures, though variations in cloud cover and decoupling could modulate them up or down, respectively, in some spots.
SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... CAD will more or less remain in place in the low levels Thursday with the high pressure sliding eastward to our north. At the same time, low pressure system will be ejecting out of the plains with warm/moist air advection. In addition, the upslope flow will result in lower clouds and perhaps some light rain or drizzle in the mountains. Highs will be cooler than today due to the lack of sun and onshore flow, with 50s widespread and the cooler spots in the 40s.
Warm and moist air advection continues Thursday night and with that we`ll see increasing chances for rain. Lows mainly in the 40s. Model guidance in good agreement that the low pressure system will track east-northeastward from near St. Louis Thursday evening to Ohio by Friday afternoon, before redeveloping near the DelMarVa late Friday and Friday night. Thus, most widespread coverage of moderate rain expected late Thursday night and Friday morning, although chances of rain will remain high into the afternoon. Half an inch of rain is likely for most of the area, with over an inch wherever the most favorable forcing aligns. We`ll also have to monitor how far north the warm sector can make it Friday afternoon. Latest guidance indicates it may approach portions of central VA and southern MD, so have maintained a slight chance of tstorms there Friday afternoon. Highs on Friday uncertain, with locations that get south of the warm front possibly heading towards 70, while northern locales near the Mason-Dixon line may struggle to reach 50. Showers will begin to slowly wind down Friday night as the low pulls away and winds turn northwesterly.
Low pressure slides northeast of the region Saturday, but lingering instability and weak vort max could produce a few stray showers still. Highs will be in the 50s to lower 60s.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... High pressure will settle into the region Sunday through early Monday. Dry and seasonable temperatures expected throughout the period.
The next storm system will move into the region midday Monday through Tuesday, bringing the chance for rain showers to the region once again.
Brief high pressure will build into the region Wednesday before the next storm system approaches Wednesday night.
