A Simple Wind Shift Makes a Huge Difference…Hottest Air Of The Summer Ahead
While today may not be the greatest of beach days, or ideal summer weather for playing outside…at least the air is comfortable. Enjoy the cool today while it lasts, because things are about to change in a very hot way! A front is currently stalled off the coast. Clouds are locked in across SNE for much of the day. We have seen periodic light showers and mist, but most of the time will be dry during the day. We will spend the day on the cooler cloudy side of this front with light onshore winds. This will keep temps in Lwr 70’s t the beaches with 70’s to near 80 father inland away from any ocean breeze. High pressure currently sitting over northern New England is supplying the cooler dry air at the low levels, and making for a great day across the far north and ME with sunshine. We can hope for a few breaks this afternoon, but it will be extremely limited. There also remains the chance of a brief passing shower or sprinkle.
Clouds will remain locked in place tonight as the front washes out south of us and high pressure shift over our head and off the coast. Winds will shift to the SSW overnight keeping lows in the 60’s to near 70 with building humidity. This all sets the stage, for a very different day on Sunday. After some early morning clouds, skies will be increasing with sunshine. SW winds will steer in a warmer wind off the land, Highs will climb into the mid 80’s with some areas in northern & western New England able to climb into the upper 80’s. Still cooler for the Cape & Islands. Dewpoint will climb into the 70s too. A very humid summer time day.
It really is a bizarre upper level pattern. The western Atlantic Ridge, which brought us our last 5 day heat wave recently took a break. Well, it’s BAAACK! It is flexing it’s muscle along the east coast once again and completely taking control of the weather across the United States! It is literally drop kicking an upper low currently in place over Kentucky back into Texas! This is something you just do not see in weather which usually travels west to east!
Either way, the high will become firmly implanted in the eastern half of the nation allowing the heat and humidity to shift east into the north east under hot warming west winds. High will be climbing into the Lwr-mid 90’s with heat indexes 100+ during the afternoon hours. A weak trough will with slightly cooler air from Canada will slide into the North east which could help to trigger afternoon storms with more WNW winds in place Thurs, Friday and Saturday…as the cooler air will clash into the hot humid air. The end of the week will hold the potential for some localized strong to severe weather. The heat will be slow to budge as it will be supplied by the huge heat ridge. The heat wave could last into Saturday, before finally being broken down during the weekend with the trough finally fully penetrating into the northeast for some welcome relief with cooler temps and lower humidity.
It is important to not that this will likely be the hottest, broadest, and mot long lasting heat wave of the summer. Please prepare to have ways to stay cool through this time ahead. The good news is the overall pattern for the rest of summer does not look as hot, so that is something which should help you get through these coming hot days ahead!
