Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 357 AM EDT Fri May 10 2024

SYNOPSIS
Showers and thunderstorms will continue through Friday as a slow moving front pushes southeast across the region.
Precipitation chances continue Saturday with yet another frontal passage, but should improve on Sunday as high pressure moves into the area. Shower and thunderstorm chances along with warmer temperatures return by the middle of next week as high pressure pushes offshore.

NEAR TERM /THROUGH TONIGHT/
An area of low pressure has now dropped south and east of our region off the VA coast. Winds are generally out of the N/NNE, and some showers are starting to develop once again across the Potomac Highlands. This is in connection with the primary trough axis, which can be seen in water vapor satellite imagery this morning. This will pivot through the region throughout the day, brining the chance for continued light showers. While a rumble of thunder can't be ruled out today, it is not very likely. High temperatures only reach into the upper 50s to low 60s for the northern half of the forecast area, so instability will be quite limited. Further south, we could see a bit less in terms of cloud cover as the trough axis pivots eastward. This could bring highs closer to 70. This would be where the best chance for thunder would be today as a result.

As the upper trough departs eastward overnight, there will still be some moisture around in the low-mid levels. This could cause some issues for those trying to view any potential auroras tonight. Generally the further south and west you go will be less in terms of cloudcover tonight.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
Another area of low pressure will move into the Great Lakes Saturday before pushing into the northeast and eventually offshore on Sunday. The cold front associated with this system will push through on Saturday, bringing yet another chance for showers and thunderstorms. Temperatures will be in the 60s for most of the area.

On Sunday it will be drier across the region as we move into the backside of the aforementioned upper-low. Can't completely rule out some showers Sunday, but should be pretty isolated in nature. Highs again will be in the 60s, perhaps a few degrees warmer than Saturday.

LONG TERM /MONDAY THROUGH THURSDAY/
Monday has the highest potential of the next seven days to be dry as mid level ridging moves overhead and surface high pressure moves offshore. Temperatures will be seasonable.

Unsettled weather returns Tuesday and Wednesday as a trough moves eastward from the mid Mississippi Valley. While the severe weather threat appears to be minimal with richer moisture suppressed closer to the Gulf Coast, a warm front draped near the area could serve as a focus for locally heavy rain. Some spread exists in potential temperatures due to rain and frontal positions, but highs will most likely run near or below normal.

00Z guidance points toward the trough/low departing east by Thursday. This could yield a drier day as high pressure builds from the north. However, another trough will be quickly approaching from the west.

AVIATION /08Z FRIDAY THROUGH TUESDAY/
Guidance continues to indicate that CIGs will drop sharply into the morning hours today, but as of now, that is occurring a bit slower than anticipated. IFR conditions continue today as precipitation chances linger.

Conditions improve to VFR on Saturday, but more showers and perhaps a thunderstorm are possible with a cold front pushing through. Winds shift to northeasterly tomorrow before becoming southerly on Saturday.

No significant weather with high pressure Monday. Sub-VFR ceilings along with showers and a few thunderstorms are possible Tuesday as a low pressure system approaches.

MARINE
Winds are generally light at the moment, but will pick up later this afternoon. SCAs have been issued for the Chesapeake Bay and lower Potomac River as a result. Winds taper off overnight into Saturday morning. Rain showers and thunderstorms could impact the waters again today, mainly in the afternoon. Winds shift to northerly Friday night before shifting to southerly for the weekend.

Southerly winds gradually increase Monday as high pressure moves offshore. Advisories may be needed Monday afternoon, continuing through Tuesday as a low pressure system approaches. Some thunderstorms are also possible by Tuesday afternoon and evening.

TIDES/COASTAL FLOODING
Tidal anomalies have remained elevated into this morning, even increasing. So, had to issued a few Coastal Flood Advisories for some of the Chesapeake Bay zones. Honestly, could see that extending up the Potomac as well if trends continue.

Water levels should drop well off by Sunday when offshore northwest flow kicks in across the area.
