Hot Week Ahead

The theme for this coming week is heat.

NAM 2-m temperatures for tomorrow mid-day (Tropical Tidbits)

The above image shows temperatures for 11 a.m. tomorrow from the NAM, where we sit in the upper 50s for much of the region and low 50s for eastern parts of New England. But notice that area of dark red in Iowa, Michigan, and Kentucky. That area of heat looks to move east as we head into the work week, bringing with it some above average temperatures.

We can see on the map for Wednesday afternoon, the red has moved into our region, bringing some temperatures that'll reach the 80s. I think the NAM may even be underdone and we could even see temperatures that reach 90 °F in spots, particularly in interior New England.

Although the air temperature will be high, we'll be feeling our first truly humid conditions of the season, making it feel muggy.

For Wednesday, we'll see dew points that reach the 70s in spots, which can be classified as oppressive. The dew point is essentially a measure of air humidity. It is the temperature that air must be cooled to to become saturated with water vapor. Here's a dew point scale explaining how conditions will feel given different dew points.

For mid-week, will be in that uncomfortable to oppressive category in spots. And lastly, here's the CFS climate model showing temperature anomalies at 500 mb in the atmosphere (the mid level of the atmosphere) for this week.

That reddish-purple that you see means it'll be hot! Enjoy your holiday weekend, and I'll have more on the possibility of severe weather during the week.
