arlwx Posted November 1, 2019 Share Posted November 1, 2019 From the latest LWX forecast: (snip) As winds subside tonight, radiational cooling will be excellent. With dewpoints in the 20s-lower 30s, stage set for a possible freeze everywhere except urban downtowns/near the Bay/Potomac. Will issue a Freeze Watch for area where growing season continues as forecast lows at or below freezing areawide except as noted above. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... High pressure this weekend, with a reinforcing trough axis/surface cold front Saturday night. Will be struggling to reach 50 degrees Sunday. If the growing season doesnt end by Saturday morning, Sunday night`s lows will likely do it. There could also be some upslope snow showers Saturday night-Sunday morning as well.

arlwx Posted November 1, 2019 Share Posted November 1, 2019 And from AKQ: (snip) .SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY/... As of 345 PM EDT Thursday... Sunny and much cooler Fri with highs in the mid to upper 50s. Around 60 is possible near the coast. Expect breezy conditions in the morning, but winds will decrease by afternoon as the high builds in and the pres gradient relaxes. Cool high pres will bring the coldest night of the season to date Fri night/Sat morning. Lows around freezing (well) inland...m-u30s central to lower to mid 40s along the coast. Potential frost/freeze headlines will be contemplated by proceeding shifts as we get closer. Continued cool and dry on Sat w/ highs in the upper 50s to lowers 60s. Another weak front pushed south late Sat night bringing another sot of cool air and colder temps Sunday with high only in the low to mid 50s. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... As of 250 PM EDT Thursday... Cool high pressure becomes centered over the area Sunday evening- Sunday night before moving offshore by Mon aftn. Sun night looks like the coldest night of the season (so far), with lows in the low- mid 30s inland/upper 30s-mid 40s close to the immediate coast. Will continue to monitor the possibility of a freeze (mainly W of I-95). Link to comment Share on other sites More sharing options...

WxUSAF Posted November 2, 2019 Author Share Posted November 2, 2019 @biodhokie and @tplbge tied for the lead with a departure of 2 days, with @biodhokie hitting BWI exactly. @Stormpc next with a departure of 3 days.

RIC Airport Posted November 3, 2019 Share Posted November 3, 2019 I would keep an eye on RIC tomorrow morning. AKQ currently has the airport reaching 33°F. Also, the low this morning was 34°F, which was a degree colder than the forecast and also colder than yesterday morning's 35°F low. 1 Link to comment Share on other sites More sharing options...

yoda Posted November 4, 2019 Share Posted November 4, 2019 LWX is no longer issuing Freeze Warnings for anyone in the CWA until next Spring... saying growing season is over for all Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1021 AM EST Mon Nov 4 2019 .NEAR TERM /THROUGH TONIGHT/... High pressure has moved offshore this morning and winds have started to shift southerly over our region. Most locations radiated very well earlier in the night, dropping to freezing or below freezing, including counties that had a Freeze Warning in effect. Therefore, the growing season has now ended for the entire NWS Baltimore/Washington forecast area. Frost and freeze headlines will no longer be issued by this office until Spring 2020.
