We reached 65 for a high Friday (normal 61) and we hit 65 on April’s Fools Day. Back in March we had 2 days at 60 or higher with 60 on the 30th and 62 on the 9th. We didn’t reach 60 or higher in February. Back in January, our warmest day was the 30th with a high of 70 (record high 72), which still stands as the highest temperature so far this year for us. We were 66 for a high January 29th and 63 on January 31st. We think we will finally we will climb above that January 30th 70 degrees and into the 70s Monday and Tuesday.

However, after what turned out to be a sunny and nice day Friday with that high of 65, we will take a step back with temperatures Saturday before the warming Sunday, Monday and Tuesday. The reason is the cooler air mass that is moving in behind the front that turned our winds to the northwest Friday afternoon and continued into early last night with peak gusts as high as 23 mph at BWI. The cooler air mass has returned with high pressure moving into northwest Pa. Saturday morning. The area of high pressure will slide across our area and move into the Atlantic late Saturday afternoon. As the center of the high slides across our area we expect plenty of sunshine and wind will not be a factor. A few harmless high and perhaps mid clouds will show up later as the warm advection between the high moving to the east and low pressure tracking from near Green Bay.

It looks like any sprinkle or shower associated with this warm advection Saturday or early Sunday morning will pass by well to our north across the far northern tier of Pa. and perhaps over into the Catskills where there may be enough forcing to overcome the dry air mass in place. As this low to the north tracks northeastward across southern Quebec Sunday and high pressure to the east gets shunted farther to the south and east, we will be picking up a milder southwest flow with average speeds of 15 mph and gusts to 25 during the midday and afternoon. We are not expecting any wet weather Sunday morning or early afternoon with a general intervals of clouds and sunshine type day, but the weak, moisture starved cold front trailing the low to the north will come southward enough to bring the chance for an isolated shower or sprinkle late Sunday or early Sunday night, but that would be more favored to our north and west. It will be a very minor event if it does happen to make it to our area.
