Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1025 AM EDT Tue Apr 14 2026
WHAT HAS CHANGED
Fire Weather SPS was issued for portions of central VA and the Shenandoah Valley through this afternoon. SPC Marginal Risk stretches across the northern half of the forecast area. Rain chances increased a bit, may need to increase more, as 12Z high res guidance comes in.
KEY MESSAGES
- Record high minimum and high maximum temperatures expected Wednesday and Thursday with an elevated fire weather risk each afternoon.
DISCUSSION
KEY MESSAGE 1...Record high minimum and high maximum temperatures expected Wednesday and Thursday with an elevated fire weather risk each afternoon.
KEY MESSAGE 1 DESCRIPTION...
Well above normal temperatures today as highs reach well into the 80s across the area, and 70s in the mountain. As in previous days, breezy southwest winds develop this afternoon with gusts around 20-25 mph. Would not be surprised if a few spots reach 90F.
The latest 12Z guidance is a bit more robust when it comes to convection moving across the northern half of the area this afternoon to evening. Given the dry low-level airmass, not expecting widespread convection. Still, steep low level lapse rates and sufficient instability, the few thunderstorms that do develop could become strong. Some of the hig res models indicate wind gusts of 40-50kt are possible. SPC has a Marginal Risk (level 1 of 5) along and north of a line from Baltimore to Winchester to Petersburg.
Upper level ridge will remain the dominant weather feature, cresting over the area Thursday supporting record warmth and dry conditions. While models have shown a slight warm bias in temperatures recently, model trends support 92-93 degs Wed and Thu respectively. Dewpoints will remain in the 50s, which is considerable comfortable. As for convection, very negligible chance of convection Wed and Thu as upper ridge crests over the area.
AVIATION /13Z TUESDAY THROUGH SATURDAY/
Gusty afternoon SW winds up to 25 kt between 17Z and 23Z.
A slight chance of a showers or thunderstorms at MRB, BWI, MTN, and maybe DCA/IAD. Will evaluate the new guidance to see if PROB30 for TSRA needs to be added for the 18Z TAFs. Otherwise, VFR conditions are expected through the rest of this week with dry conditions. Some risk of convection Friday.
MARINE
SCA issued for all the waters valid 17Z-00Z. Conditions will likely repeat itself both Wed and Thu. Risk of thunderstorms Fri.
FIRE WEATHER
Elevated fire weather risk today through Thu due to very warm temperatures, marginally low humidities, and gusty afternoon winds of 20-25 mph. Wed and Thu will have the lowest humidities with values in the mid 20s. An RFW may be needed for both Wed and Thu.
CLIMATE
Record hi max seem unlikely today, but record hi low seem more likely. Wed and Thu likely to see new records set as highs reach 92-93 degs.
Many daily records are likely to be broken this week, for both high temperatures and warm low temperatures. Some stations could tie or set their all-time high temperature and warm low temperature records for the month of April.
