After another dusting of snow in the northern tier departs early Wednesday, a couple of dry and brighter days are expected during Wednesday and much of Thursday with moderating temperatures. A complex storm will steadily evolve into a nor’easter Thursday night and Friday threatening the eastern half of the Commonwealth with wet snow or a wintry mix. The Poconos have the best chance for more than a half of foot of snow. Once this storm exits late Friday, the weekend will be dominated by high pressure, which after a couple of chilly mornings will yield to milder afternoons. The next significant precipitation is expected on Monday with rain overspreading the state, probably starting as an icy mix in the northern and central sections. A cool front will bring more seasonable conditions for the middle and latter half of next week. The period from February 12-19 should be dominated by near to above average temperatures and several risks of precipitation as an active southern branch of the jet stream sends disturbances toward the East Coast. It is possible that sections of the state will receive a couple of moderate snowfalls. Odds favor another cold snap during the last week of the month.
While the longer range computer guidance points to rather mild weather building during March, the analog forecasts indicate at least a 10 day spell of stormy, wintry weather during the middle of next month. Early indications show heat and drought are likely again in the southwest and western Plains as well as the interior Southeast this coming summer.
