Daily Weather Pattern Discussion...Summer And Winter, All In A Day!

Hello this is Junior Meteorologist Kyle Elliott with our daily weather pattern discussion...and believe it or not, we could get a taste of summer and a blast of winter in only one day this coming Wednesday/Thursday as highs on Wednesday may approach 65-70 degrees in southern Pennsylvania before crashing to the middle 30s with heavy snow on Wednesday night. On the same token, the "heavy snow part" might not happen as there is still great uncertainty to whether or not anybody in Pennsylvania will see anything more than a few snow flurries on Wednesday night...but the part about 65-70 degrees looks quite certain for southern Pennsylvania tomorrow into midday Wednesday. A strengthening, complex storm system coming out of the Tennessee River Valley and the Plains states tonight will track east and northeastward throughout the night...spawning a line of severe thunderstorms around the Mid-Mississippi Valley region across Indiana this evening and later tonight. Some of the storms could rotate as a warm front is also in that vicinity...so if a tornado warming is issued for your area, SEEK SHELTER IMMEDIATELY as tornadoes, especially nighttime tornadoes, can be very life-threatening. Anyways, the line of severe storms will move eastward throughout the day tomorrow...with heavy rains, hail, and damaging winds reaching western Ohio by tomorrow evening. After that, a problem develops...one of the models continues to take the storm through northern Pennsylvania with no snow south of New York State, but the other model develops another low pressure system in VA/MD and moves it off the New Jersey coastline by Wednesday night. If the first model is right, a line of severe thunderstorms will continue to move eastward across Pennsylvania on Wednesday as temperatures fall from the 60s to the 40s with the passage of the thunderstorms. If the second model is right, the line of thunderstorms will probably fall apart temporarily before transporting their moisture to the coast and exploding again in southern Pennsylvania and northern Maryland. The problem with the second solution, though, is that the cold air would charge into the storm on the coast, therefore possibly causing a narrow but nearly unbearably heavy band of snowfall to develop across southern and eastern Pennsylvania Wednesday night. If that were to be the case and the cold could catch the storm on the coast, somebody around the York/Harrisbur/Lancaster areas could pick up a foot of snow in a 4-6 hour period with temporary blizzard conditions...but right now, I think that scenario is still far-out and I am not biting on it just yet. At any rate, though, it will be something that needs to be monitored as we go throughout tomorrow, so I'll make sure to keep ya'll posted with the latest updates and information. For now, though, have a great night, enjoy the warm weather tomorrow across southern PA, and I'll talk to ya'll then!
