Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 359 AM EDT Sun Jun 2 2024

SYNOPSIS
High pressure will slide offshore early today. Shower and thunderstorm chances return today into Monday as a quick moving low pressure system passes through the region. Dry conditions briefly return with high pressure Tuesday before shower and thunderstorm chances increase with a series of fronts mid to late next week.

NEAR TERM /THROUGH TONIGHT/
Low-level moisture will continue to build in across the Mid- Atlantic today as a result of departing high pressure and an incoming weak area of low pressure. Light returns on radar have been observed this morning across the Allegheny Front. These showers will continue to progress further east throughout the day. Models have been a bit slower to the timing of the showers compared to what is being realized so far so have increased PoPs a bit quicker to account for this instance.

For today, expect off and on showers and an isolated thunderstorm to be possible, especially along and west of the Blue Ridge Mountains. For any thunderstorms, severity should remain tame due to weak instability parameters to work with (weak flow, non-steep lapse rates). Afternoon highs will climb into the upper 70s to low 80s for most lower elevations and upper 60s for the mountains. Showers may linger into the overnight hours with lows dropping down into the upper 50s to mid 60s.

SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
By Monday, we'll continue to hold chances for showers and an isolated thunderstorm, especially in the afternoon. The coverage and intensity continues to look fairly tame given the mesoscale setup. Afternoon highs will increase as a result of southwesterly flow into the low to mid 80s for most areas aside from the mountains where mid 70s will be more common. Breaks in the clouds will build in throughout Monday night with lows dipping down into the upper 50s in the mountains to low to mid 60s further east towards the waters.

Brief upper ridging will alleviate PoPs on Tuesday with only a 20 to 30 percent chance for an isolated shower or thunderstorm.
Highs are expected to be in the upper 70s to low 80s for most areas with increasing cloud coverage as a result of incoming onshore flow to the area. Low end PoPs continue through the overnight hours with lows dropping down into the low to mid 60s.



LONG TERM /WEDNESDAY THROUGH SATURDAY/
Guidance has come into better agreement on Wednesday as the ECMWF has trended more progressive, bringing warm frontal precip to the region by Wednesday afternoon. The cold front swings through Thursday into Friday with another round of showers and t-storms. Guidance remains inconsistent on if the upper trough associated with the frontal system cuts off as it moves into the Great Lakes with the ECMWF lagging behind the GFS and Canadian with this development. As a result, the 12z Euro solution is drier behind the cold front on Friday, while the GFS/CMC have some lingering shower activity Friday and into the weekend.

AVIATION /08Z SUNDAY THROUGH THURSDAY/
Prevailing VFR conditions are expected into the beginning of the work week. For today, light variable winds will increase a bit with the departing area of high pressure. Cannot rule out a brief ceiling restriction with any shower or isolated thunderstorm that crosses the terminals. VFR conditions likely continue into Tuesday with weak upper ridging nearby building in across the area. Nonetheless, cannot completely rule out a stray shower or isolated thunderstorm.

Shower and thunderstorms are possible both Wednesday and Thursday, especially during the afternoon and evening, which could bring restrictions to the terminals.

MARINE
A Small Craft Advisory remains in effect for the lower waters of the central Chesapeake Bay through early this morning. Cannot completely rule out the need for a Special Marine Warning for any strong storms that cross the waters later today but the magnitude and intensity should be below severe thunderstorm warning criteria.

Sub-SCA conditions are expected Tuesday and Wednesday. Showers and thunderstorms moving over the waters during the afternoon and evening hours could bring stronger gusts especially on Wednesday and Thursday afternoon. Special Marine Warnings cannot be ruled out during this period.

TIDES/COASTAL FLOODING
Anamolies will continue to rise over the next few days with increasing onshore flow allowing some of the more sensitive sites to be around action stage with an outside chance for minor tidal flooding.

LWX WATCHES/WARNINGS/ADVISORIES
DC...None.
MD...None.
VA...None.
WV...None.
MARINE...Small Craft Advisory until 10 AM EDT this morning for Anz533- 543.
