-- Changed Discussion --
Weakening line of storms moving southeast as of 730 PM. Main thing driving severe storms is a combination of fast movement and rain falling into a very warm and low dewpoint airmass. Dewpoints most of the afternoon were around 48 degrees, but some dewpoints noted late afternoon in the upper 30s. Anyway, several reports of wind gust to 48 knots. Expect most of the showers and storms to be south of our area by Midnight. Main threat is strong winds, and perhaps some small hail. It has been wet lately, but so far speed of storms has kept rainfall amts down.

&& .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... I did edge temperatures up a bit on Monday, given current guidance. Earlier discussion below. High pressure and low pwat air will bring fair and dry weather for early this week. Daytime highs remain mild for this time of year in the 60-75F range. Lows will trend warmer night/night from 35-45F Monday night to 45-55F Tuesday night. Forecast soundings on Monday show drier air aloft, with some potential of mixing down towards the sfc, thus have continued to lean towards lower dewpoints in this timeframe. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... A mild but wet week in store for much of the upcoming week. A cold front moves east of the area by Monday. An area of weak high pressure gives way to warm front on Wednesday, followed by an occluded front on Thursday. Main change to this section is cooler temperatures for Wednesday into Thursday, we had in the fcst earlier. After Thursday, several secondary cold fronts will move across the area with cooler temperatures by late week. While the showers will likely end by the start of the weekend, there will be the potential for colder temperatures and frost by then. Inserted patchy frost into the fcst for late Friday night across the north. No real signal for a 3 day period of much needed dry weather. && .AVIATION /00Z MONDAY THROUGH FRIDAY/...

Line of thunderstorms oriented west to east through the central airspace late this evening will slide slowly southeast through 04Z. Storms are generally weakening and affecting KUNV at this time with limited impacts. Most likely next impacts would be KMDT/KLNS and secondarily KJST/KAOO. Breezy-to-gusty winds will before decreasing overnight after the cold frontal passage. LLWS remains possible along the Alleghenies (JST/AOO/UNV) between 00Z-06Z Monday before becoming less of a factor later in the overnight period. Outlook... Mon-Tue...Predominantly VFR. Tue PM...Thickening clouds, light rain and possible restrictions developing. Wed-Fri...SHRA/PM TSRA with brief restrictions expected.
