.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.
