High pressure is fully in command of our weekend weather. It will slowly slide down from Canada over the course of the weekend sitting right over us providing sun filled skies for Saturday & Sunday. Temperatures are slowly beginning to moderate across the interior, but a the coast a cooler NE wind at the surface remains. Winds off the 41 degree water can make the coast line be quite a bit cooler, than from the milder temperatures inland. Everyone will bask in the sunshine, but the beaches will struggle to warm with highs climbing into the Lwr-mid 50's before cooling off in the afternoon with a stiffening sea breeze. Highs inland will be quite a bit different with highs in the Lwr 60's Saturday. and even climbing into the Lwr 70's Sunday. The warmest spots will be in the western valleys. Places like Lebanon, Keene and Plymouth will feel the warmest during the afternoon...the farthest away from the cooler onshore wind. Meanwhile, despite the amazing weather...Red Flag warnings are up for critical fire conditions thanks to low relative humidity, breezy winds, mild temps and dry brush. Also the Pollen count is quite high as well. So there still are some environmental conditions to be aware of.
The blocking pattern continues in the atmosphere, but it will start to breakdown over the course of the weekend. No pattern can last forever. It appears Marathon Monday will be the warmest day of the stretch. Sunshine will hold on for a good portion of the day, along with a mild WSW wind. Temperatures should be able to climb into the Lwr 70's, during the afternoon, especially across southern New Hampshire.. A little warm for the runners in the Marathon, but an absolute delight for the spectators! A cold front will arrive late in the day into the evening which will come with clouds and a a few showers.
Behind this front we can expect breezy and cooler weather to push into place Tuesday into Wednesday with a mix of sun and building clouds and the risk of a few spot shower with a trough in place across the Northeast for the midweek. This cooler air aloft will help to destabilize the air with the heating of the day. Building afternoon clouds will be possible both Tues and Wed.The cooler air will be quickly lifting out by Thursday with temps right back to near 70. A flattening of the flow will take over and much warmer air will begin to invade the nation. Temperatures will average above normal for most of the United States and warmer mild Pacific air will be able to cross the country. The end of April from the 21st through the 28th looks like will have plenty of warmth along with it. So the Spring is definitely here to stay this time! There is no looking back! Forward!
