September featured warm and wet conditions across much of Central PA. 🌡️Above average warmth was largely driven by very mild nighttime temperatures. 🌧️Measurable rainfall was recorded on nearly half of the days in the month.

A high pressure system over the Northeast and mid-Atlantic States will promote sunny and beautiful conditions across the LSV today. Winds will be light, and high temps should reach the mid-to-upper 60s. Also notice the river valley #fog in central and northern PA.

A high pressure system of Canadian origin will settle into the Commonwealth during the 2nd half of the weekend. Winds will subside Sat night, & Sun will turn out sunny & unseasonably cool with high temps between 55-60°F. The 1st widespread #frost of the season occurs Sat night.

1/2 Behind this evening's cold front, NNW winds of 12-25 mph with gusts up to 40 mph will usher a dramatically cooler and drier air mass into the Commonwealth on Sat. Skies will gradually clear from NW-to-SE throughout the day, and dewpoints will fall by some 40°F over 24 hours..

2/2 Temps will also drop into the upper 40s to low 50s by daybreak and then hover in the low-to-mid 50s for the rest of the day. Factor in the wind, and it'll feel like it's in the 40s. Grab a sweatshirt, heavy jacket or winter coat for @millersvilleu's #homecoming parade!

A potent cold front will traverse southeastern PA & the LSV from NW-to-SE between ~3-8 PM & be accompanied by a line of heavy, gusty showers capable of producing locally damaging wind gusts up to 60 mph. Tree- & powerline damage, as well as isolated power outages, may occur.

SW winds of 10-20 mph in advance of a potent cold front will pump warm and humid air back into the LSV today. AM clouds will give way to several hours of PM sun prior to the arrival of a low-topped squall line, and highs will be near 80°F with dewpoints in the mid-to-upper 60s.

A weak cold front will traverse the Commonwealth from NW-to-SE from this afternoon into tonight. Heavy showers & embedded T-storms are rumbling through western PA this morning, but only a few lighter showers will make it over the Apps into northern MD, southeastern PA & the LSV.

Westerly winds of 7-14 mph will continue to push warm & humid air into the LSV today. Despite increasing clouds, highs will reach the low-to-mid 80s with dewpoints in the mid-to-upper 60s. The #October14 record high temp of 84°F from 1975 at @millersvilleu will be challenged.
