Synopsis for the tidal potomac and md portion of the chesapeake bay -
a surface trough will linger west of the waters near the blue ridge mountains this afternoon before drifting southeastward across the waters tonight into Thursday. This trough may ignite multiple rounds of showers and Thunderstorms. A cold front brings potential for more widespread strong Thunderstorms Friday into Friday night. Small craft advisories may be needed in the wake of the front Friday night into Saturday morning. High pressure looks to return for at least the first half of this weekend resulting in lower rain chances before another frontal system approaches early next week. Small craft advisories may be needed in southerly channeling Sunday, though there is uncertainty in the timing of the arrival of the next front.

WHAT HAS CHANGED
Have removed mention of showers and thunderstorms along/east of I-95 as the boundary layer stabilizes behind the earlier convection. Otherwise, a convective threat remains for Thursday and Friday, with the latter being more active as a cold front pushes through the region.
KEY MESSAGES
- 1) Storm chances diminish tonight ahead of more active weather during subsequent days.
- 2) Hot and humid conditions return Thursday and Friday with a daily threat for strong to severe thunderstorms.
- 3) Drier conditions expected to start this weekend, before chances for showers and storms return by early next week.
DISCUSSION
KEY MESSAGE 1...Storm chances diminish tonight ahead of more active weather during subsequent days.
While sub-severe in nature, a mixture of storm clusters and convective lines moved across the region during the afternoon to early evening hours. What remains of this thunderstorm activity has pushed into southeastern Delaware and coastal New Jersey.
While a few spotty showers have popped up across north-central Maryland, expect a dry start to the overnight period. The only exception would the Allegheny Front which sees some increase in showers after midnight. While the boundary layer will stabilize, a spotty thunderstorm or two is possible given any elevated instability. Areas off to the east will stay dry overnight with some patchy fog, particularly near regions that saw appreciable rainfall. Tonight's low temperatures are forecast to range from the mid 60s to low 70s.
KEY MESSAGE 2...Hot and humid conditions return Thursday and Friday with a daily threat for strong to severe thunderstorms.
Mid-level dry air will build in associated with shortwave- ridging on Thursday. Thursday's convective potential seems that will be suppressed in coverage, but hot and humid conditions will likely overcome any weak capping and may result in a threat of locally damaging downburst winds.
Severe threat Fri appears to be significant greater as ridging breaks down and height falls spread across the area supporting large scale ascent. Hotter and even more humid conditions combined with an approaching cold front will result in more widespread thunderstorm coverage, potentially severe given large CAPE values in excess of 2000 J/kg.
KEY MESSAGE 3...Drier conditions expected to start this weekend, before chances for showers and storms return by early next week.
Cold front will cross the area Fri evening with storms ending giving a dry less humid day Saturday. A weak cold front will cross the area Sunday afternoon with more showers and thunderstorms, although the amount of moisture and instability does not look overly strong.
Broad trough across the Great Lks and east of the Rockies will keep the risk of showers next week, but instability looks meager to support severe thunderstorms at this time.
AVIATION /01Z THURSDAY THROUGH MONDAY/
Some patchy fog may develop tonight in areas that received more appreciable rain and see some clearing/lighter winds. Otherwise, any overnight shower threat will likely be confined to the Allegheny Front.
Prevailing VFR conditions are expected on both Thursday and Friday. Thunderstorm coverage is uncertain Thursday afternoon and evening, but any storm could contain hail and strong wind gusts. There is a higher chance of strong to severe thunderstorms Friday afternoon and evening as a cold front approaches. Winds will be fairly light out of the west or southwest both days.
VFR conditions are predominantly expected through the weekend, with some reduced conditions possible on Sunday evening associated with a low chance of showers and thunderstorms. Winds flow out of the NW before shifting S Sunday.
MARINE
Earlier Small Craft Advisories were allowed to drop off as wind gusts have fallen below the necessary thresholds. Thus, there are no marine hazards overnight. A recurrence of SMWs may be needed in thunderstorms Thursday afternoon and evening and then again Friday afternoon and evening due to severe thunderstorms.
A break in hazards Saturday and Sunday before the next possibility of advisories and warnings become possible Sunday night through the middle of next week.
CLIMATE
Temperatures are expected to soar to as much as 15 to 20 degrees above average Thursday and Friday. This approaches or exceeds daily record values at some sites.
