Synopsis for the tidal potomac and md portion of the chesapeake bay -
high pressure will Wedge into the region for the end of the week, then move offshore over the weekend. Additional small craft advisories will likely be needed for portions of the waters Saturday afternoons. Extensions may be needed due to southerly channeling Sunday into early next week. The next substantial front to cross the waters looks to arrive by Tuesday bringing renewed chances for showers and Thunderstorms.

SYNOPSIS
High pressure moves offshore today. A warm front attached to low pressure over the Great Lakes moves by Saturday. Highs pressure returns for Sunday and into next week. Another low and front arrives for Tuesday.

NEAR TERM /THROUGH TONIGHT/
High pressure is centered over northern New England and southern Quebec early this morning, with a light pressure gradient over our region. Dew points dropped notably yesterday, so with dry air, light winds and clear skies, it looks as though radiational cooling should be excellent through dawn. Will watch obs closely to see if freeze/frost headlines need to be cancelled anywhere, but doesn't currently look like we'll need headline expansion anywhere given temps are running near to slightly above expectations.

Otherwise, looks like a dry and mostly sunny day as the high very slowly drifts eastward through the day. The sun should allow rapid warming but the light southeasterly to easterly flow on the south side of the high will limit the climb in temps especially close to the ocean. Overall expect highs in the 60s inland to 50s near the coast.

Tonight should stay mostly clear, but the easterly flow likely moistens up the low levels just enough that, when combined with some approaching high clouds ahead of a warm front and the warmer start plus warm advection aloft, should limit the drop.
Might need some frost headlines but think another widespread freeze is off the table... possibly for the rest of the season? We'll see, but either way, milder than tonight. Lows mostly 30s to low 40s.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
A transition to early summer readings Saturday and Sunday. An upper ridge will build across the area thru the period and as this happens, low pressure moves by to the north, bringing a warm front thru on Saturday. There will be plenty of clouds along the frontal boundary, increasing through the day and into the overnight period. The high elevations of the Poconos and NW New Jersey could see an isolated light shower during the day, but the best chance for showers (20-30%) will be along the I-78 corridor and points north.

Mild and dry weather will be around for Sunday. Following the warm front, a deep southerly flow will arrive over the area, so increasing warmth and humidity is expected. Highs Sunday will be in the upper 70s/low 80s in most spots, but cooler near the shore and up across the Poconos. A mild night expected as well with lows only reaching the mid 50s to around 60.

LONG TERM /MONDAY THROUGH THURSDAY/
Very warm temperatures for late spring will remain in place as the upper ridge starts out across the eastern US to start off the work week. High temperatures will likely be the warmest thus far this season with much of the region reaching the low to mid 80s! Gradually, this ridge weakens and allows more scattered shortwave energy to arrive across the area. For Tuesday and into Wednesday, a cold front will approach the area and then wash out as it moves through. Some scattered showers and thunderstorms will certainly be possible, mainly Tuesday afternoon and Tuesday night, but overall probabilities remain around the 25-45% range.

Another system will approach the region Thursday, though there remains quite a bit of model spread in timing and evolution.
Sticking close to our consensus blend, leaving a 20-30% chance for showers.

Temperatures remain above average in the mid 70s to low 80s through Thursday.

AVIATION /07Z FRIDAY THROUGH TUESDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas...

Through today...VFR. East to southeast winds increasing to near 5-10 kts. High confidence.

Tonight...VFR. East to southeast winds dropping to 5 kts or less. High confidence.

Outlook...

Saturday through Monday...VFR prevail. A few moments of sub-VFR conditions possible Saturday night as a warm front pushes through with scattered showers. Otherwise, a dry forecast.

Tuesday...VFR to start with sub-VFR conditions potentially arriving in the afternoon and evening with the arrival of a weak cold front.

MARINE
Seas are diminishing and should be in the 2-4 foot range through tonight with an east to southeast wind around 10 kts with gusts up to 15 kts. Fair weather.

Outlook...

Saturday through Tuesday... Winds and seas will remain below SCA criteria through the period. Fair weather expected.

FIRE WEATHER
RH values will be in the 25-30% range today. However, with winds so low, around 10 MPH or less, the threat for the rapid spread of wildfire remains low. The morning shift will take another look and coordinate with partners to see if any statements are needed.

CLIMATE
A few records could be approached early this morning.
