| Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 1002am EDT Tuesday Jun 2 2026 .WHAT HAS CHANGED... No changes to the forecast at this time. .KEY MESSAGES... 1) Cooler than normal today with a spotty mountain shower or t- storm. Quiet weather with a warming trend midweek. 2) Temperatures increase late in the week while a strong cold front brings widespread showers and possibly a few thunderstorms late this weekend. KEY MESSAGE 1...Cooler than normal today with a spotty mountain shower or t-storm. Quiet weather with a warming trend midweek. A sharpened trough and weak piece of shortwave energy remains draped across the Alleghenies and southwest VA this morning. This piece of energy will gradually swing east this afternoon and into the evening as broad high pressure (1024-1028 mb) high pressure over central Canada/Great Lakes region pushes south. As a result, expect a few brief spotty showers and isolated t-storms this morning and into the early afternoon period. Rain amounts will be limited with most locations remaining dry and under partly/mostly sunny skies. The greatest confidence for showers will be tied to the mountains (i.e Alleghenies & central Blue Ridge) due in part to orographic lifting. Highs today will push into the upper 60s and mid 70s (low to mid 60s mountains). Lows tonight will fall back into the upper 40s and low tom id 50s. Meanwhile, coastal low pressure will develop along the Gulf Coast today before ejecting east toward the coastal GA/SC. Current 06z ensemble and deterministic guidance shoves this system further south given the broad high building south from the Great Lakes/Ohio River Valley. As a result, expect dry conditions for both Wednesday and Thursday along with temperatures closer to seasonal norms. Highs Wednesday will into the upper 70s and low 80s (upper 60s mountains) with mid to upper 80s (low 70s mountains) expected Thursday. Lows Wednesday night will fall back into the mid top upper 50s (low 50s mountains). These values climb back into the upper 50s and mid 60s under return flow Thursday night into Friday morning. KEY MESSAGE 2...Temperatures increase late in the week while a strong cold front brings widespread showers and possibly a few thunderstorms late this weekend. Upper-level ridging will persist into Friday and Saturday, causing further warming throughout the region with afternoon highs in the low 90s. However, conditions should remain dry with dewpoints likely remaining fairly steady, keeping the heat index close to the actual air temperature. Rain chances remain minimal through this period with relatively light WSW winds. Meanwhile, a deep upper-level trough is expected to form over the Great Lakes over the weekend and then slowly track through the Northeast region. A strong cold front stemming from this system will travel through the Mid-Atlantic, causing widespread chances for rain showers and possibly a few thunderstorms between Sunday and Monday. Uncertainty still remains high with this system, as the synoptic setup and timing still diverges significantly between the GFS, ECMWF, and the ICON models. Overall, the timing of this front has trended later into the weekend over the past several model runs, and severe probabilities remain low as of this time. Temperatures likely remain above normal until the front eventually passes offshore. Marine Still seeing some occasional 20 to 25 kt gusts over the open waters of the bay and lower tidal Potomac this afternoon. Winds will drop back below SCA (Small Craft Advisory) levels later this afternoon and into the evening as high pressure builds overhead. No marine hazards are expected Wednesday and THursday as high pressure moves overhead. Some near SCA (Small Craft Advisory) level southerly channeling is possible Thursday evening into Friday morning over the middle and lower waters although confidence is low at this time. Winds will be out of the north/northeast through Wednesday before switching back to the south and southwest Thursday. Marginal SCA (Small Craft Advisory) conditions are possible Friday evening through early Saturday morning, then again on Sunday evening as a trough moves through the region along with scattered rain showers and possibly a thunderstorm. Winds generally flow southwesterly through Sunday. Tides / Coastal Flooding Water levels will likely rise again through this evening, the magnitude of which will depend on the position and strength of low pressure developing off the coast. Additional minor tidal flooding is most probable at Annapolis with Wednesday morning's high tide, but will monitor any potential quicker water rises given the return of onshore flow tonight. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...None. MD...None. VA...None. WV...None. Marine Small Craft Advisory until 11am EDT this morning for ANZ534- 537-543. |
