DISCUSSION

Issued at 205 AM EDT Wed Apr 8 2026

Currently, quasi-zonal flow is in place aloft with 1,035mb high pressure centered over New England. Subsidence will keep dry air in place with an even cooler morning than previous days. Throughout the day, high pressure will shift further to the east, increasing southerly flow. Slight height rises will begin a warming trend with temperatures rising into the 70s for most. Low RH values are expected again, but weak 850mb flow and MSLP gradient will keep winds more limited in our area. By Thursday, further height rises are expected with fairly zonal flow remaining aloft. Even lower RH values in the 20s can be expected, but low-level flow and the MSLP gradient will remain weak.

By Friday into Saturday, a trough/closed low will move onshore from the Pacific with increasing ridging and another area of high pressure in the east. This will further the warming trend with high temperatures likely rising into the 80s for most by Saturday. On Sunday, troughing will move through the Rockies with an initial surface low developing in the northern Great Plains and then tracking into Canada. This will increase southerly flow and height rises in the eastern U.S. with much of the area rising well into the 80s. High pressure to the east will keep dry conditions in place in our area. By Monday, troughing will dig down as it ejects out of the Rockies with another surface low/frontal boundary eventually moving towards the region. High pressure and southerly flow will keep warm and dry conditions in place on Monday before rain chances return for Tuesday.
