SYNOPSIS. Low pressure will slowly drift across eastern Canada through the rest of the week. High pressure will build across the deep south today, then offshore of the southeast coast on Friday. A couple of weak surface troughs will cross the area through Friday as well. An area of low pressure will impact the area Saturday night through Sunday, then move into the Canadian Maritimes Monday. High pressure briefly affects the Mid-Atlantic late Monday into Tuesday, before shifting offshore by Wednesday.

NEAR TERM /THROUGH TONIGHT/. 900 AM Update: Allowed the Freeze Warning to expire as temperatures continue to climb through the 30s. Given the current forecast and since some guidance is even a little colder for some areas tonight, went with a Freeze Watch for most of eastern PA (Carbon and Monroe counties have not started the growing season yet), most of northern NJ and down through the NJ Pine Barrens. The winds may end up decoupling more overnight at least outside of the urban centers which could result in some frost development. Will wait until the afternoon full forecast issuance to make any decisions on any Frost Advisories. Otherwise, tweaked some of the hourly grids to keep them current. Increased the cloud cover some through the afternoon as areas of stratocumulus are expected to fill in given the cold air aloft.

Otherwise, our region will spend today and tonight sandwiched between the departing closed low (responsible for the cold front yesterday) and the surface high building towards the southeastern U.S. This leaves our region with a tight pressure gradient today and tonight. Consequently, cold air advection will continue through this period. Thus, the main concern remains freeze again tonight.

Despite model soundings depicting a very deep mixing layer today (mixing up to 700 mb), winds aloft should be decreasing (as compared to yesterday), so agree with the previous shift that the potential for wind advisory conditions (gusts at or above 40 kt/46 mph) is very low. Nevertheless, still anticipating rather breezy conditions with west to northwesterly winds of 15-25 mph with gusts up to 35-40 mph.

Thanks to the cold air advection, highs will be 15 to 20 degrees below normal, and about 20 to 25 degrees lower than the pre-cold front highs from Wednesday. Highs should be mostly in the 40s and 50s, though the higher elevations of the southern Poconos and NW NJ may not get out of the 30s.

SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/. Another dry and breezy day are expected on Friday, although it is not expected to be as windy as Thursday. Low pressure continues to slowly drift across eastern Canada, while high pressure builds offshore of the southeast coast. This keeps a steady flow across the area, and with good mixing, gusty winds are expected during the day of at least 20-25 mph. A weak surface trough is expected to move across the area during the day, but will only bring additional cloud cover through the day. Quiet conditions are expected to continue into Friday night.

LONG TERM /SATURDAY THROUGH WEDNESDAY/. The beginning of the long term is expected to be the most active of the extended period. An area of low pressure will be moving across the Tennessee River Valley on Saturday, before making its way across the Mid-Atlantic region Saturday night into Sunday. Meanwhile, another low pressure moving across the Deep South and offshore of the southeast coast is forecast to merge with the first low as the lift toward the Mid Atlantic region Saturday night into Sunday. As the two lows merge, enhanced lift will move across the area as multiple short waves/vorticity impulses pass overtop. This lift, combined with enhanced moisture is expected to lead to an extended period of rainfall. Rainfall amounts are generally in the 0.50-0.75 inches according to much of he forecast guidance, which will likely fall over a several hour time period, so no widespread flood issues are expected.

The rest of the long term period is expected to be dry, although Monday will be quite breezy as the low pressure drifts northward, and high pressure builds in from the west. The high pressure briefly builds across the Mid Atlantic Tuesday, before shifting offshore Tuesday into Tuesday night.

Guidance is indicating a warm front lifting across the area around Wednesday, but this warm frontal passage is expected to be dry.

AVIATION /13Z THURSDAY THROUGH MONDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . VFR with a scattered to broken cloud deck developing (around 5000 feet AGL). Northwesterly winds 15-20 knots with gusts up to 30 knots. High confidence.

Tonight . VFR with decreasing clouds. Northwest or west winds around 10 knots. High confidence.

Outlook .

Friday-Friday night . VFR conditions expected. West winds 10-15 knots, gusts 20-25 knots, becoming light and variable overnight. High confidence.

Saturday . VFR conditions as rain approaches the area from the south. South winds 5-10 knots, with gusts 15-20 knots. High confidence.

Saturday night-Sunday . Conditions lower to MVFR or IFR as rainfall spreads across the area from south to north. Winds will be variable from site to site, depending on the track of a surface low. On Sunday however, winds will become gusty out of the northwest with gusts 20- 30 knots. Moderate confidence.

Sunday night-Monday . VFR conditions expected. Gusty northwest winds 15-25 knots. Moderate confidence.

MARINE. The Gale Warning remains in effect through early this evening for all waters. Wind speeds should increase later this morning as stronger winds mix down. Northwesterly winds gusting around 35 kts are expected from late morning through most, if not all of the afternoon. Seas 4-6 feet across the ocean waters. Winds should diminish this evening, though SCA conditions are likely to continue through most if not all of Thursday night.

OUTLOOK .

Friday . Small Craft Advisory conditions likely.

Friday night-Saturday . Conditions fall back below advisory levels Friday night and continue through Saturday.

Saturday night-Sunday . Conditions likely to increase to advisory levels as an area of low pressure passes near the area.

Sunday night-Monday . Advisory levels winds likely remain as low pressure remains to our north and high pressure builds to our west.

FIRE WEATHER. Windy and dry conditions are expected today across the area. Most areas received less than one half inch of rain yesterday, so fuels in many areas will be drying. We will be coordinating with state fire partners later this morning to ascertain the current state of fuels. Winds are forecast to gust to 30+ mph and minimum relative humidity values are forecast to be between 20 and 30 percent. Another dry day is forecast on Friday as RH values could drop into the low 20, while winds could gust 25-30 mph at times.

PHI WATCHES/WARNINGS/ADVISORIES. PA . Freeze Watch from late tonight through Friday morning for PAZ060>062-101>106. NJ . Freeze Watch from late tonight through Friday morning for NJZ001-007>010-012-013-015-020>022-027. DE . None. MD . None. MARINE . Gale Warning until 8 PM EDT this evening for ANZ430-431- 450>455.
