Weather: Holiday heat to moderate late week

ITHACA, NY — The start of the week will be cooking as much as your barbecue as temperatures climb into the 90s for the end of May. However, a mid-week cold front should bring temperatures done to more seasonable values ​​in time for the next weekend and the Ithaca Festival. I thought for sure that there was a hex in place to prevent good weather and the festival from happening at the same time, but I digress.

Your Weekly Weather

Warm and pleasantly tranquil conditions are in place thanks to an area of ​​high pressure centered south of Bermuda. Given clockwise flow around highs in the Northern Hemisphere, that means warm southerly air is being advected into the Northeast. Skies are mostly sunny this Sunday, with highs topping out in the low 80s, a tad above average for late May. Thankfully, dewpoints remain on the low side, in the lower 50s, so it still feels comfortable outdoors.

A broad low pressure storm system will strengthen as it moves northeastward over the Great Plains tonight and tomorrow, and that’s going to tighten the pressure gradient with the offshore high. That tightening of the gradient will induce a stronger southerly flow, and result in warmer temperatures for the start of the week. Tonight will be quiet with a few passing clouds and lows in the upper 50s.
