SYNOPSIS. Chilly weekend weather will give way to a big warmup by midweek. Dry weather will persist through Wednesday, but a slow moving front will increase rain chances toward the end of this week with temperatures trending seasonably cooler into next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. Skies have cleared as low-dewpoint air remains across the area this evening. Winds are also decreasing as the axis of high pressure moves overhead, reducing the pressure gradient. Clear skies, dry air, and diminishing wind will make for effective radiational cooling for most if not all of the night. High clouds will move in after midnight, but probably not thick enough to hinder radiational cooling. Min temps will range from 5 to 10 above up north to the upper teens to near 20 south.

SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/. After a cold start, the much advertised warm-up begins on Monday, as an anomalous upper level ridge builds over the East Coast and winds back from NW to SW. Highs on Monday will reach the low to mid 40s northeast to the low to mid 50s southwest. Dwpts will only rise slightly compared to Sunday.

The warm up will continue through the middle of next week, as upper-level riding persists over the eastern United States. The 12z/07 GEFS projects 850mb temperatures to rise well above normal by the middle of next week, with the anomalies peaking Wednesday or Thursday. There is a good chance that highs will topping 60 degrees for much of central PA each of those days.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. A cold front approaching from the Upper Midwest will bring increasing clouds by Thursday, and introduce a chc of rain showers across the northwestern counties. This front will slowly slip southeastward and across the area on Friday, accompanied by a continued chc of showers.

There remains some disagreement in the medium-range models as to how quickly the front will pass south of central PA, and exactly how cold it will get behind the front. The 12z/07 operational ECMWF pushes the front south of the area Friday night and projects a reinforcing shot of unseasonably chilly air for Sunday. Meanwhile, the 12z/07 GFS stalls the front just south of the Mason-Dixon line next weekend, before bringing a significant surge of moisture towards the area next Sunday or Monday.

Fortunately, this is still a week away and we'll have plenty of time to monitor models trends between now and then. Regardless, it looks like the mild weather will come to an end by next weekend, with a trend back to normal /or even below normal/ temperatures.

AVIATION /00Z MONDAY THROUGH FRIDAY/. High pressure will build into the region tonight, ensuring widespread VFR conditions and light winds. A warm front will push into the area Monday, accompanied by increasing clouds, especially over the northwest half of the state. However, all model guidance indicates ceiling heights will be VFR. The arrival of strong west winds aloft, combined with relatively light winds at the surface, could result in low level wind shear over northern Pa Monday evening.

Outlook .

Tue . Early AM LLWS possible. AM low cigs possible NW Mtns.

Wed . Patchy AM fog possible eastern Pa.

Thu . Evening low cigs/showers possible NW Mtns.

Fri . AM low cigs/showers possible, mainly W Mtns.

FIRE WEATHER. Spring fire season is starting in parts of CPA with a few brush fires reported in the last two days. The latest fuel moisture assessment from PA BOF partners on Thursday, March 4th indicated no critical fuel moisture conditions through the rest of this weekend.

Modified arctic high pressure extending from the Upper Great Lakes south to the Ohio Valley will build southeast into PA tonight and Monday, bringing an end to the gusty winds.

Surface dewpoints may drop into the single digits this afternoon, but moisten a bit on Monday.

Dry and much milder conditions will occur into the middle of the upcoming week along with increasing humidity. Relatively light wind Monday and Tuesday will freshen to 10 to 15 mph with gusts into the 20 to 25 mph range from the south on Wednesday.

CLIMATE. Daylight saving time (EST->EDT) begins on Sunday, March 14th.

The first day of astronomical spring (vernal equinox 2021) will be at 5:37 A.M. EDT on Saturday, March 20th.

CTP WATCHES/WARNINGS/ADVISORIES. None.
