Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 933 AM EDT Wed May 15 2024

SYNOPSIS
Unsettled weather conditions look to continue today as slow moving low pressure and it's associated front cross the region. Weak high pressure will bring drier weather conditions to the area on both Thursday and Friday. Another slow moving low pressure system will bring additional shower and thunderstorm chances for the weekend before weak high pressure returns early next week.

NEAR TERM /THROUGH TONIGHT/
930 AM Update: Showers and areas of drizzle continue to be widespread across the area this morning. Noticeable breaks in the clouds are being observed across portions of north-central WV. Some subtle breaks are also showing up across southern VA, this may end up further north into central VA later today.
Expect very gradual improvements throughout the day.

Previous Discussion Follows: One area of low pressure is near Evansville IN this morning with a secondary low developing near Hampton Roads. Ascent with the coastal low continues to result in light to moderate rain for the I-95 corridor, while a dry slow moved over the western areas. There have even been a few breaks in the clouds, so some patchy fog is trying to form in the western valleys. Some showers and drizzle are likely to fill back in through the morning hours as the upper trough approaches and the coastal low moves northeast, increasing moisture aloft.

Showers associated with the coastal low may tend to decrease during the midday hours, but light drizzle may continue until early evening thanks to onshore flow. Additional showers under the upper trough may cross southwestern portions of the CWA this afternoon. This area has the best chance for a few breaks in the clouds and some weak instability to develop, so an isolated thunderstorm is possible. Have removed the mention of thunder elsewhere. Temperatures will struggle to rise under the low overcast, with high temperatures only in the mid 60s.

The upper trough will absorb the coastal low tonight, causing it to stall off the coast. Chances for rain will decrease, although showers could linger near the Chesapeake closer to the low.
Skies will likely remain cloudy through the night, but there could be some breaks in western portions of the area, leading to fog development. Lows will be in the mid 50s to near 60.

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
The low will remain off the coast on Thursday while ridging aloft attempts to build in from the west. Clouds may be slow to clear across the I-95 corridor, but even where clouds do break, a scattered to broken cumulus field should fill in. Most of the day will be dry, but lingering moisture and localized convergence could result in a few showers. Cloudier locations in the east may struggle to reach 70, while western areas will have highs in the mid to upper 70s. The upper ridge axis will move overhead Thursday night, leading to dry conditions and lows in the 50s.

The next trough will be taking a similar west to east path across the mid Mississippi Valley on Friday. Leading axis of forcing will approach Friday afternoon into Friday night, bringing an increasing chance of rain. The highest chance for showers and an isolated thunderstorm will be west of the Blue Ridge. Temperatures will remain seasonable.

LONG TERM /SATURDAY THROUGH TUESDAY/
Once again it's another unsettled weekend with increased shower and thunderstorm chances across the region. Our active weather pattern continues with 1-2 days of drier weather followed by 2-3 days of stormy conditions.

The next low pressure system and it's associated cold frontal boundary will approach from the Ohio River Valley Saturday into Sunday. 00z model guidance continues to show subtle discrepancies in regards to the placement of the low and associated surface fronts as it pushes east. Current thinking is that the low will cut across the central Appalachians Saturday afternoon before pushing off the VA/NC coast Sunday.

Expect fairly widespread shower and thunderstorm activity Saturday with decreasing coverage as the low pushes east Sunday. Severe weather does not appear to be a concern at this point although one or two strong thunderstorms cannot be ruled out if CAPE/shear can be maximized within the peak heating period. This will be the case Sunday where a few breaks in the clouds are possible (mainly over the mountains) as drier air tries to push back in. Localized flooding could be the bigger concern given repetitive rounds of rain throughout the week and rich moisture (high PWATS around the 90th percentile) funneling in. For those with plans outdoors Saturday appears to be the wettest compared to Sunday.

Mid level ridging/weak high pressure briefly build back into the area Monday and Tuesday bringing slightly drier conditions. Another front and shortwave trough of low pressure will follow for Wednesday and Thursday with renewed chances for showers and thunderstorms

Below normal high temperatures can be expected this weekend due to added clouds and increased rain chances. Highs Saturday will push into the mid to upper 60s with lows in the mid to upper 50s. Sunday is slightly warmer with highs in the upper 60s and low 70s.
Temperatures rebound through the early and middle part of next week, eventually reaching the low 80s. Overnight lows settle in the mid 50s to lower 60s.

AVIATION /14Z WEDNESDAY THROUGH SUNDAY/
Low pressure is located near Hampton Roads this morning, leading to rain across the metro areas. A dry slot has resulted in rain ending temporarily to the west. Standard MOS guidance has been too pessimistic with ceilings, but do bring IFR back into the TAFs toward dawn based on HRRR probabilities. Likewise have leaned more optimistically into MVFR conditions this afternoon based on these probabilities. Showers may fill back in for a time this morning, tapering more to drizzle this afternoon. One caveat is that if drizzle is more persistent, IFR ceilings and even visibilities could linger. Easterly winds do become more northerly this evening, which should lead to drying conditions.
However, MVFR to IFR ceilings will likely persist with the low lingering off the coast. Some breaks in the clouds could occur at MRB, which could lead to fog.

Low ceilings should gradually lift Thursday and could scatter out in some locations. However, there are indications low ceilings and/or fog may redevelop Thursday night into Friday morning. The next system will be approach late Friday, increasing the chance for showers and sub-VFR ceilings, especially Friday night.

Sub-VFR conditions can be expected through Saturday as another low pressure system passes through the region. Shower activity will increase across the terminals Saturday morning with perhaps a few thunderstorms Saturday afternoon as the surface low passes to the south. Slightly drier air and VFR conditions return Sunday into Tuesday with weak high pressure overhead. Additional sub-VFR conditions are possible Wednesday and Thursday next week as another front and shortwave low pressure system cross the region.

MARINE
Low pressure is located near Hampton Roads this morning and will gradually lift to the northeast today. Easterly winds have been verifying on the higher side of the envelope, with gusts around 30 kt in the middle bay and lower Potomac. While not quite that strong, forecasts do have stronger winds spreading northward this morning. Therefore have issued a Small Craft Advisory for all zones today except for the upper Potomac, which may be too far west to feel these effects. Showers and drizzle may also reduce visibility at times.

The low will remain off the coast tonight into Thursday. An advisory will remain in effect for the bay and lower Potomac through the night as winds become more northerly. Deeper mixing should ensue Thursday with the wind field still in place, so the SCA will expand to all waters. Winds are forecast to gradually diminish Thursday night, but the advisory will likely need to be extended for some zones. Overall lighter winds are expected Friday and Friday night as weak high pressure moves across the area.

A brief period of SCA conditions remain possible Saturday afternoon into Saturday night as an area of low pressure passes just south of the region. This will be especially true over middle and lower portions of the bay and lower tidal Potomac where a bit more channeling could occur. Numerous showers and perhaps a few thunderstorms will accompany this system through Saturday into early Sunday.

Slightly drier conditions are expected Sunday although SCA conditions will likely remain. Winds will change from the south and southeast Saturday to the east and northeast Sunday as low pressure pushes off the VA/NC coast. Marginal SCA conditions will linger into Monday as weak high pressure builds over the region.

TIDES/COASTAL FLOODING
Easterly winds will keep water levels elevated in the Chesapeake Bay and Tidal Potomac through this afternoon. Expect additional minor coastal flooding during this morning's high tide cycle at Annapolis and Straits Point, and possibly DC SW Waterfront, although all three locations may be marginal.

As an area of low pressure moves east of the area later today, winds become northeast, then north. This should result in quickly decreasing water levels and reduced coastal flood threat.

Beyond today, the next threat for coastal flooding appears to be Friday into the weekend as south to southeasterly flow returns ahead of an approaching low pressure system from the Ohio River Valley.
