A Wet Week Ahead

Synopsis:

 

Unfortunately, unsettled weather we saw this week will continue through all of next week, bringing the chance for rain every couple days or so. With all the moisture in the air, temps will not change much. Expect highs around 70 and lows in the 50's, which is mild for this time of year. The only days that look to be rain-free are Monday and Thursday, so get outside while you can! Otherwise, be sure to have your umbrella handy - it's going to be a wet week.

 

Short-Term:

 

Expect batches of precipitation to begin affecting southern/central portions of PA very late tonight/early tomorrow morning. These will then dissipate and give way to the warm front from the stronger low pressure system to our souhwest. According to current GFS models, this system will then swing slowly up through the Ohio River Valley and weaken. After the warm front hits on Tuesday, the remnants of the cold front will rumble through on Wednesday and produce off and on rain throughout the day.

 

Long-Term:

 

After the fronts from the dying low pressure system have moved through, whatever remnants of that system will be sucked into the next, much stronger low pressure system up to our northwest in Canada. It looks to develop along a trough (associated with a low even farther to the north) and rapidly intensify over Wisconsin and Michigan. As it makes its way northwestward over the Great Lakes and into Canada, this storm's cold front has the potential to produce precipitation, and possibly some storms, from the Ohio River Valley up into Pennsylvania and New York and across northern New England.

 

This system currently looks to develop and strengthen significantly over a short period of time (1200Z on Thursday to 1200Z on Friday), and should be monitored closely for the potential for strong storms and heavier precipitation.
