Area Forecast Discussion National Weather Service State College PA 729 AM EDT Sun Apr 21 2024

SYNOPSIS
An upper level trough with unseasonably cold air aloft will swing through eastern Canada and the northeastern states late this weekend. A frost or freeze is expected in many areas of Central and Northern PA this morning and again Monday morning as high pressure moves overhead and the sky clears. Showers return to the forecast for late Tues through Wed.

NEAR TERM /UNTIL 7 PM THIS EVENING/
Got much colder locally than fcst as temps dropped into the u20s in Centre County. The clouds have now closed in and, like they did elsewhere, raised the temps slightly already, even before sunrise. Expect the multi-layered clouds to break up some before noon, but really do so in the afternoon and move off to the east in the late aftn and evening.

Prev...
Low cloud cover has spread across the northern half of the CWA and some of the Laurel Highlands as of 08Z. The temperature fall has just about halted there. These clouds will try to get into the frost advy area, but it has likely already formed even if it does go away before sunrise. Temps should start to warm up everywhere after sunrise despite the thickening high clouds.
The high clouds will slide to the east later this morning as the wave over the Carolinas scoots off the coast. Nothing more than a sprinkle is possible without good forcing this morning/early aftn over the nrn tier. Maxes should be 45-55F.

SHORT TERM /7 PM THIS EVENING THROUGH 6 PM MONDAY/
Clearing should be just about complete tonight. Thicknesses and 9H/8H temps remain static thru Mon PM. Therefore, we could see temps very similar to Sun AM again on Monday morning. Now, there won't be clouds (high or low altitude) like Sun AM which should allow them to go even a deg or two colder still. The one trick may be how much wind is left overnight - there may be a little breeze. Therefore, we don't have quite enough confidence to post another frost advy for Mon morning just yet. However, the progged mins are between 31-33F for the ridge and valley region (which is roughly the part of PA that is SE of the Allegheny Front and NW of the Lower Susquehanna Valley).
Therefore, even if the wind stays up, they could get a freeze (without any visible frost).

High pressure nosing in from the west crests over the Appalachian Mountains on Mon Temps rise nicely on Mon aftn- night. This should keep clouds away, but allow for a light WNW wind. 8H temps rise a bit back to near 0C. All this should help temps into the 50s over most of the area and lower 60s in the SE where they'll have a downslope llvl flow.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
Model guidance all supports dry conditions Monday night through most of Tuesday, as high pressure and an associated low-pwat air mass overhead starts to slip a little to the east. However, upper level troughing does support below average temperatures on Tues. Some frost is again possible Tues AM, but as slight warm advection starts aloft, the temps might not be able to get quite as cold as Mon AM. The wind does look light for most of the CWA

A decent warmup looks likely Tuesday, as high pressure moves off the east coast. Medium range guidance all points to a chance of showers and a subsequent cool down associated with a cold front passage Tuesday night into Wed AM. The moisture return ahead of the front looks unimpressive, but strong forcing ahead of a potent upper level shortwave suggests a good chance of rain. Latest plumes support a general 0.2 to 0.4 inch rainfall.

It appears there will be another chance of a frost/freeze Thu and Fri AM, as Canadian High Pressure builds over the region.
Those with agricultural interests should keep an eye on the forecast for the end of next week.

The next chance of rain will come Friday night into Saturday associated with low pressure lifting into the Grt Lks and the associated warm front approaching PA.

AVIATION /12Z SUNDAY THROUGH THURSDAY/
VFR conds are expected to continue through 00Z Monday with high (> 90%) confidence. Some low-level clouds are expected to return during the morning/early afternoon hours on Sunday with ceilings above 5000ft AGL expected.

Winds will slowly be on the decrease overnight at 300-340 with recent observations outlining some gusts up to 20-25kts across SE PA. Winds are expected to dip below 10kts sustained by 2Z Sunday and continue into the early afternoon hours. Later in the TAF period, there is moderate (50-60%) confidence in gusts between 15-20kts at 280-320 after 18Z Sunday at all airfields outside of MDT/LNS.

Outlook...

Mon...No sig wx expected.

Tue...Slight chance of evening showers/cig reductions NW Mtns.

Wed...Showers move in west-to-east from rain early, continues throughout the day. TSRA possible SW late PM.

Thu...Clearing as high pressure builds into the area.
