Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 353 AM EDT Thu Jun 13 2024

SYNOPSIS
High pressure slowly pushes offshore today. A cold front tracks through the area on Friday leading to renewed shower and thunderstorm chances. High pressure settles over the area this weekend with lower humidity. Next week looks to become hot as a very strong upper ridge builds over the region.

NEAR TERM /THROUGH TONIGHT/
A residual area of high pressure remains across the Mid-Atlantic region this morning. However, with light winds out of the south to southwest, early morning temperatures are certainly up from previous nights. Per 07Z/3 AM observations, most locations are in the low/mid 60s, locally down up in the upper 50s for places that have fully decoupled. Skies remain mostly clear although a few spots have seen some passing mid-level clouds.

Expect a much warmer day today with increasing heights aloft and persistent low-level warm advection. 1000-500 mb thicknesses increase by around 6 to 8 dm over the 24 hour period heading into this afternoon. Net warming in the lower half of the troposphere will support increasing temperatures this afternoon.
Current forecast highs are in the upper 80s, accompanied by a few spotty 90 degree readings. To escape the heat, the mountains are forecast to see temperatures in the mid/upper 70s. Subtle lift in the quasi-zonal flow may spark some isolated afternoon showers over the area. Some activity could become locally enhanced around mesoscale features like bay and river breezes.
Do not expect updrafts to become strong/tall enough to produce any lightning activity. Any showers wane after dark with a mild night ahead.

The forecast calls for low temperatures in mid/upper 60s, with near 60 degrees along the Alleghenies.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
A brief bout of summertime heat persists into Friday before a cold front scours out all of the heat and humidity. The latest forecast package brings this cold front across the I-95 corridor between 5-8 PM Friday evening.

A period of south to southwesterly warm advection will sufficiently moisten the low-levels of the atmosphere. Dew points are forecast to rise into the low/mid 60s which helps contribute to mixed-layer CAPE values to around 1,000 J/kg. For early summertime standards, this is actually on the lower end.
However, forcing from the grazing trough coupled with low-level convergence from the cold front should aid in scattered showers and thunderstorms. Forecast soundings depict very steep low- level lapse rates (near dry adiabatic) but with rather poor mid- level lapse rates (5-5.5 C/km). Ultimately, updrafts may struggle to get tall as they encounter this more lackluster portion of the profile. Additionally, nearly unidirectional westerlies may cause some drier air to mix in which would possibly impede thunderstorm formation. With all that said, a Slight risk is in place from central Maryland northeastward into southeastern Pennsylvania. Damaging winds are the main hazard, accompanied by the usual heavy downpours and frequent lightning strikes. A Marginal risk is in place elsewhere across the region. Any convection exits to the Eastern Shore by just after midnight. Low temperatures stay mild although post-frontal northwesterlies will ensue overnight.

High pressure settles over the Great Lakes and northeastern U.S.
on Saturday. This will favor a slight cooling trend, less humidity, and a dry forecast. High temperatures are set to hit the 80s with 70s in mountain locales. However, dew points return to the 50s which removes the humidity factor from the equation.
Sunny skies are expected with the ridge in charge. This sets the stages for a tranquil evening and night with low temperatures falling into the 50s to low 60s.

LONG TERM /SUNDAY THROUGH WEDNESDAY/
A dome of modified Canadian high pressure will settle across interior New England down into the Carolinas on Sunday morning.
The 1024-1026 mb pressures are fairly impressive for mid-June standards. Ample radiational cooling effects should make for a cool start to the morning. Around sunrise, temperatures are forecast to start off in the mid 50s to low 60s. The mentioned ridge is expected to exit offshore by midday which allows for a return southerly flow to kick in over the local area. Expect fairly seasonable temperatures with readings in the mid/upper 80s, locally in the mid/upper 70s across the mountains. A few additional clouds are possible as high cirrus spread in from upstream convection. Nighttime conditions trend milder with the south-southeasterly warm advection.

The work week ahead will be comprised of a lengthy period of above average temperatures. The culprit is a large subtropical ridge which settles over the Eastern Seaboard. Ensembles agree on the presence of this ridge, but do differ with placement, strength, and longevity. Additional, some instability-driven convection is possible which would play a role in the daily temperature forecasts. How all these factors play out will ultimately dictate just how pronounced and lengthy this heat wave will be.

Overall forecast numbers have dropped by a degree or two.
However, widespread mid 90s seem quite likely which is accompanied by increasing humidity levels. Heat index values should near the century mark each afternoon. Even mountain locations will be quite toasty as daily high temperatures push up into the mid 80s. Overnight low temperatures should also stay quite warm with little relief expected. Most see overnight lows in the low 70s, with mid 70s near the urban hubs. Even the Allegheny Front should see lows in the mid 60s. Forecast lows will generally be around 8 to 14 degrees above average next week.

Heat products may be needed at times, particularly given the duration of this potential heat wave. Ensembles favor this lasting through the remainder of the work week, potentially even into parts of next weekend.

AVIATION /07Z THURSDAY THROUGH MONDAY/
Some locally patchy fog is possible across the favored river and mountain valleys. This would include KCHO and KMRB where MVFR visibilities are possible between 5-9 AM this morning. Any fog should quickly burn off by a few hours after sunrise. Otherwise, VFR conditions are expected through tonight with southerly afternoon gusts up to 15 knots. Isolated showers are possible this afternoon, but these should not cause any restrictions.
Light southerlies continue into tonight around the western periphery of high pressure off the coast. Another round of patchy fog may impact the area late tonight into early Friday.

Although the first half of the day will likely bring VFR conditions, an approaching cold front carries a risk for showers and thunderstorms. Some of these could become locally severe, especially for locations north of I-66/U.S. 50. A period of restrictions are possible where thunderstorms reside. In the wake of the cold front, winds eventually shift to northwesterly on Friday evening. Mainly sunny skies are likely on Saturday as high pressure returns. This comes with winds that meander between northwesterly and northeasterly. Afternoon gusts could approach 15 knots before subsiding after dusk.

VFR conditions are expected on Sunday underneath mostly sunny skies. A retreating area of high pressure will yield a shift over to mainly south to southeasterly flow on Sunday afternoon/evening. By Monday, winds become mainly southerly with increasing heat and humidity. This combination may spark a few showers and thunderstorms. However, outside of any of these showers, VFR conditions are expected at the area terminals.

MARINE
High pressure persists across the area waters this morning with light south-southwesterlies gusting to around 5 to 10 knots.
Expect southerly channeling this afternoon into tonight with gusts up to 20 knots. As such, Small Craft Advisories are in effect across the Chesapeake Bay and its adjoining tributaries, as well as the lower tidal Potomac.

On Friday, additional southerly channeling could bring some locations to near 18 knots at times. However, there is not enough confidence to hoist additional advisories. An approaching cold front increases the risk of strong to severe thunderstorms between around 5-11 PM (later for the more southern/eastern locations). Special Marine Warnings would be needed for the stronger storms. Behind the cold front, winds shift to northerly. A period of northerly channeling may require Small Craft Advisories for the first half of Saturday. High pressure eventually weakens winds through the remainder of the day.

Expect light winds to start off on Sunday morning thanks to the ridge of surface high pressure. This gradually moves offshore leading to a shift to south-southeasterlies during the second half of Sunday. Mainly southerlies are likely on Monday with some channeling effects possible over the Chesapeake Bay. Thus, Small Craft Advisories may be needed at times Monday afternoon into portions of the night. Any thunderstorm chances appear confined to locations off to the west of the waters.

TIDES/COASTAL FLOODING
Current tidal anomalies remain slightly elevated, generally ranging between 0.5 to 0.7 feet. At this point, only the sensitive locations like Annapolis and Straits Point are expected to reach Action stage during the next several high tides. Water levels do quickly drop off over the weekend behind a cold front. North to northwesterly flow should push a lot of the excess water back toward the south.
