WHAT HAS CHANGED
No significant changes.
KEY MESSAGES
1. Record breaking warmth continues through today, with above normal temperatures into the first half of the weekend.
2. Elevated fire weather potential today.
3. A period of increased shower chances later this weekend.
Much colder temperatures later this weekend and especially early next week, with the greatest risk for frost and/or freeze conditions during Monday night into early Tuesday morning.
DISCUSSION
KEY MESSAGE 1...Record breaking warmth continues through today, with above normal temperatures into the first half of the weekend.
With high pressure situated over the Atlantic Ocean and the warm front well north of the Mid-Atlantic region, continued warmth is expected through today. Very warm air aloft coupled with warm air at surface levels will allow temperatures to be as much as 15 to 30 degrees above normal through the end of the week.
Highs today will be similar to Wednesday's, in the mid 80s to low 90s. Dewpoints should mix out a bit more today compared to Wednesday. This could support slightly warmer temperatures, however thicker cirrus could limit heating a bit more. In any case, still expecting several high temperature and warmest low temperature records to fall today. See the Climate Section below for temperature records stats.
As is typical in spring though, temperatures along/near the coast will be significantly cooler due to the colder sea surface temperatures and diurnal sea breeze. While a weak surface front passes through early Friday morning, temperatures will stay well above normal into Saturday with highs mainly in the mid 70s to mid 80s.
KEY MESSAGE 2...Elevated fire weather potential today.
A period of fire weather conditions supportive of fire spread is forecast today, as very warm and dry conditions continue.
MinRH values will drop into the 25-35% range for many locales across eastern PA, NJ and Delmarva. This will be accompanied by southwest winds around 10-15 mph with gusts up to 20 mph in the afternoon. Due to lack of recent rainfall, there is some potential for fire spread. While these conditions do not meet Red Flag Warning criteria, a Special Weather Statement will be warranted for some areas.
This is of elevated concern for ongoing drought/abnormally dry conditions over much of the area, which will likely only get worse after this week. While there are a few instances of showers over the next couple of days, any rainfall totals will be minimal.
KEY MESSAGE 3...A period of increased shower chances later this weekend. Much colder temperatures later this weekend and especially early next week, with the greatest risk for frost and/or freeze conditions during Monday night into early Tuesday morning.
A backdoor cold front may arrive into at least parts of our region during Saturday and/or Saturday night. Some guidance is a little more robust with this sneaking in as the low-level flow is more from the northeast and east ahead of an approaching warm front. Given significant inland boundary layer warming during the day Saturday, the leading edge of the cooling may surge inland faster.
We then turn our attention to a strong upper-level trough that will settle across most of the East during the second half of this weekend and early next week. A strong cold front will precede this trough and slide across our region late Saturday night into Sunday morning. A weak area of low pressure may also develop along the front in our vicinity. As the main trough axis hangs back farther to the west, much of the shower activity may occur behind the cold front. Given the strength of the incoming upper-level trough, forcing for ascent should be strong enough to result in increasing shower coverage for a time. The thunder risk at this time looks rather low given the timing of the front. This will be much needed rain, and it will also result in a significant cool down into early next week. A gusty wind will also occur especially in the wake of the cold front, and this should limit frost formation Sunday night and early Monday morning. Much lighter winds and a colder air mass with high pressure settling overhead should set the stage for frost and/or freeze conditions Monday night into early Tuesday morning.
Temperatures then rebound Tuesday afternoon and especially on Wednesday.
AVIATION /12Z THURSDAY THROUGH MONDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.
Today...VFR with broken cirrus. Southwest winds increasing to around 10-15 kts with gusts up to 20 kts. High confidence.
Tonight...Mainly VFR with a slight chance of showers, especially for RDG/ABE. Southwest winds shifting west to northwest near 10 kts with low level wind shear possible around frontal passage. High confidence in prevailing conditions.
Outlook...

Saturday and Sunday...Some showers Saturday night and especially Sunday morning with a period of sub-VFR conditions possible. West-northwest wind gusts up to 25 knots Sunday afternoon.
Monday...VFR. Northwest wind gusts up to 25 knots, diminishing in the evening.
MARINE
Southwest winds of 10-15 kts with gusts around 20 kt and seas around 2-4 feet are expected through tonight. Some isolated gusts up to 25 kts and seas nearing 5 feet are possible, but not expecting these conditions to prevail. Thus, no advisory in effect through tonight at this time. Fair weather.
Outlook...
Friday and Saturday...The conditions are anticipated to be below Small Craft Advisory criteria.
Sunday and Monday...A period of Small Craft Advisory conditions possible.
CLIMATE
