Synopsis for the tidal potomac and md portion of the chesapeake bay -
high pressure building across the area through tonight will bring very warm temperatures and dry conditions. A cold front crosses the waters Tuesday into Wednesday bringing chances for showers and Thunderstorms. High pressure briefly returns Thursday before another front crosses the local waters over the weekend. Small craft advisories may be needed Tuesday afternoon to evening, and again on Friday.

SYNOPSIS
An upper-level high pressure ridge will build along the East coast bringing unseasonably warm temperatures today. A backdoor cold front will approach this evening and hang across our region on Tuesday, while an upper-level trough approaches.
Showers and thunderstorms return later Tuesday and possibly linger into Wednesday, before weak high pressure builds in for Thursday. A cold front could approach from the west later Friday and pass through during the weekend.
NEAR TERM /THROUGH TONIGHT/
As of 6:00AM...Conditions are quiet across the region. No major changes to the forecast at this time; forecast remains on track.
For Today...500 mb heights look to be near 580 dam, values more typical of summertime. At the surface, high pressure will remain centered offshore of the Carolinas, helping to advect warmer and more moist air into the region. The result of this will be very warm day for the region with much above normal temperatures.
High temperatures are expected to soar into the mid to upper 80s in most interior locations under partly cloudy skies. Highs in the more urbanized areas could top out closer to 90 degrees, though readings of 90 degrees or higher still appear unlikely. Northwest flow will add a downsloping component to the winds and thus also help to boost temperatures locally near the urban corridor. The offshore wind will also allow for a notable warmup even along the immediate coast, with highs getting to the low to mid 70s before a sea breeze kicks in.
As the gradient flow weakens and shifts eventually to the southwest then south, a sea breeze will likely make significant inland progress into the I-95 corridor and perhaps even farther inland from there during the evening. This will cool temperatures off into the 70s and 60s by late evening. Dewpoints will be near 60F, so the Heat Index won't be much different than the air temperature. No heat headlines are anticipated. With some additional weak shortwave energy rounding the top of the upper-level ridge, some isolated showers or storm are possible north of Philly, however the subsidence will be quite strong and any convection will likely struggle to materialize.
Monday night...Overall, another warm night anticipated. A backdoor front will sag over the region from the north/northeast and become stationary. Where exactly the front ends up stalling will be a forecast challenge. Low temperatures expected to be in the low to mid 60s southwest of the front and in the mid to upper 50s northeast of the front for most locations. Mostly cloudy skies anticipated for areas northeast of the front; mostly clear to partly cloud skies anticipated for areas southwest of the front.
With some lingering shortwave energy, some isolated showers remain possible, mainly for our northern areas. Model soundings support fog development once again during the early morning hours; cannot rule out patchy fog development once again.
SHORT TERM /TUESDAY THROUGH WEDNESDAY/
High pressure starts to give way on Tuesday as an upper level trough digs into the Carolinas region. This starts to being a return of some moisture to the area however the moisture looks to ride along the top of the departing ridge. The net effect is that Tuesday remains abnormally warm across DelMarVa and southern PA/NJ with some near normal temps working in over the Poconos and northern NJ. Cloud cover will likely be the determining factor in how warm or cold temps end up as guidance suggests a stalled front should hang slightly to the north Trenton.
Aside from the temperatures Tuesday, we will have to keep an eye out for showers and thunderstorms developing across central and eastern PA ahead of the approaching upper-level trough. The southern stream portion of the trough will split and hang back across the Tennessee Valley, with the northern stream shortwave tending to 'pull-up' and weaken as it approaches. Additionally, a new surface low will develop around SE PA into northern Delaware on Tuesday, before tracking ENE offshore Tuesday night.
All of this will tend to limit instability and forcing from the Delaware Valley eastward across NJ, so that storms will eventually weaken as they head into that airmass. That said, guidance does indicate 1000-2000 j/kg of CAPE and perhaps 30-35 kt of deep layer shear, so there is potential for some strong to possible severe thunderstorms to develop. However currently the missing ingredient is a trigger to fire the storms. Do not expect widespread storms though, with fairly limited rainfall area-wide Tuesday afternoon and evening.
By Wednesday the low pressure pushes offshore, however while temps drop, humidities levels increase. Thus with a slowing of the upper- level trough passage there may be a few spotty showers lingering along with a fair amount of cloud- cover.
Lowered high temperatures a bit from NBM guidance otherwise area-wide, as much of our region will be more exposed to cooler east- northeast flow, keeping highs mainly in the low to mid 70s from the Delaware Valley west, and in the 60s toward the shore.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/
High pressure returns for the middle of the week and should persist through the end of the week. While upper- level ridging will start to shift eastward across the Appalachians toward Friday, another surface high pressing southward from New England may bring another backdoor front with associated cold air advection, keeping at least much of the shore and perhaps much of northern NJ in the 60s to low 70s. Sensible weather is expected to be dry with fairly plentiful sunshine, and slightly above normal temperatures farther southwest from the marine influence. Some showers may threaten as early as late in the day Friday, with increasing clouds toward eastern PA, as the next storm system approaches. That looks to be another surface low lifting across the Great Lakes, with a weakening surface cold front heading our way over the weekend. Stayed with NBM POPs.
Not looking like a washout, but some scattered showers and possibly some thunderstorms possible. Temperatures should remain pretty close to typical values for early May, if not slightly above normal.
AVIATION /12Z MONDAY THROUGH FRIDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today...VFR conditions with few to scattered clouds. Winds initially from the W/NW near 5-10 kts will back with time. Sea breeze will develop and penetrate further inland with time during the afternoon/evening, causing winds to shift out of the S/SSE. Slight chance to chance (20-40%) of isolated/scattered showers in the afternoon into the evening, mainly for sites north of KPHL. High confidence overall, lower confidence in details (e.g., exact sea breeze timing).
Tonight...Mainly VFR for most sites. However, guidance indicates a stratus layer could move in from the northeast. How far this layer gets will be determined by where the front ends up stalling. CIGS could lower to 10k ft or less for sites north of KPNE in the later half of end of the period (i.e., KABE/KTTN).
Some patchy fog may once again occur at some sites. Mainly variable or easterly winds 5 kts or less. Low confidence.
Outlook...
Tuesday and Wednesday...Mainly VFR but occasional MVFR and even briefly/locally IFR conditions possible in scattered showers and thunderstorms later Tuesday afternoon and evening. Some of those showers may linger into Wednesday.
Thursday and Friday...VFR conditions expected.
MARINE
No marine headlines anticipated through Monday night. WSW winds 5-10 kts will shift briefly W then NW this early morning due to a land breeze. Winds shift to the SSE/S by late morning then hold S through Monday night. Seas 2-3 feet.
Outlook...
Winds and seas expected to be sub SCA through the period.
Generally south to southwest winds through Wednesday veering to the northeast then onshore late Wednesday. Fairly persistent onshore flow anticipated through the end of the week. Medium chance (40-50%) of scattered showers with isolated thunderstorms Tuesday night into Wednesday morning.
