After a much-deserved few day break from the oppressive humidity that we suffered through last week, we’re unfortunately headed back into a tropical airmass as moisture continues to surge northward from the Gulf of Mexico, and adjacent parts of the tropical Atlantic. Dew points this morning are still reasonable, in the mid 60’s for most of the area, but by this evening, dew points will range from 65 in the north, to over 70 in the south, back into the “oppressive” range.
Along with the increase in humidity will come an increase in cloud cover, as well as an increase in precipitation chances. Satellite imagery shows plenty of sunshine across the area this morning, and high clouds just to our south/west. These high clouds will filter into the area this morning, resulting in a transition to overcast skies by lunchtime. Coastal fog will also continue, with only slightly improved visibility this afternoon. These clouds will help keep temps down in spite of the humidity, with highs ranging from 80 in areas northeast of Augusta to 70 in the White Mountains.
We’ll remain under the influence of strong high pressure in the Western Atlantic, so widespread shower/thunderstorm activity is not expected. However, a pop up shower or storm is possible late in the day across New Hampshire, with heavy rain being the primary threat.
Wetter weather is expected tomorrow.
