Spring Warmup on Tap Across the Northeast

by Will Cano | News Contributor


April Showers have been the common occurrence so far this month across the Northeast. So, the question is, will it bring May flowers?

Unlike the colloquial saying describes, there is one more vital piece to this phenomena occurring: warmth. 

While temperatures haven't been freezing across the Northeast these past few weeks, they haven't been sunny and toasty either. Average to slightly-below average temperatures have been commonplace. Philadelphia has been averaging high temperatures about two degrees Fahrenheit below average, for example. This weather is making many people forget that summer is only two months away. 

That perspective will change this week as multiple northeast cities will make runs into the 70s and 80s for days on end. 

On Monday, a high pressure set up over the Eastern US, setting the stage for warm, calm weather to settle into the region. While the high pressure won't stick, multiple storm systems will pass to the north of the Great Lakes, and their resulting warm fronts will allow warm, moist air to seep northward.

This will most notably be the case on Wednesday night, as the strongest warm front will drive its way as far north as Maine. This will allow for a resemblance to summer night-time temperatures overnight in multiple cities. For example, in Albany, New York, the forecasted low temperature on Wednesday night is 55 degrees. Albany's average night-time temperature in June is 56 degrees. 

Temperatures will be 15 to 20 degrees above average on Thursday as well. To add to the summer sentiment, humid air will accompany the warmth as well.

Meteorologists measure humidity using "Dew Points", or the temperature at which water condenses based on how much water is already in the air. The higher the dew point, the more uncomfortably muggy the air is. Dew Points will be in the 50s and 60s from north to south on Thursday, and this excess humidity will lead to thunderstorms dotting the region in the afternoon.

So, will these toasty temperatures last? Not for long. The thunderstorms on Thursday will be ushered by a cold front, leading to cooler and calmer air settling into the region on Friday. However, more cold fronts are expected over the following days, and many calculations point to a stark cooldown beginning Sunday into next week. 

Some models even point to a cooler trend lasting multiple weeks ahead. This is due to a split in the polar vortex, allowing cooler-than-average air to permanently reside over the eastern part of the country.

So, for now, enjoy the warm temperatures and the flowers that are sure to benefit from it.
