.DISCUSSION...
Issued at 122 AM EDT Tue Apr 7 2026

Currently, mid/upper troughing is centered to our northeast with a 
Canadian High diving into the northern U.S. Ahead of this Canadian 
High, a cold front is moving through our region. With the lack of 
moisture, the main result will be northerly flow and a continuation 
of cooler and drier conditions. Low relative humidity values in the 
20s are expected again today. By tonight, the high will be centered 
over the eastern Great Lakes, leading to stronger subsidence and 
lighter winds in our area. Patchy frost will be more likely into 
Wednesday morning, especially in northeastern parts of the area. 
Height rises will promote the start of a warming trend on Wednesday 
with continued dry conditions during the day. By Thursday, the flow 
aloft will become more zonal with high pressure having pushed off 
to the east. This will keep conditions dry and seasonally mild. 

Friday through the weekend, the pattern will become more amplified 
as a Pacific trough with stronger upstream flow moves onshore. This 
will lead to increasing ridging across the eastern U.S., further 
enhancing the warming trend from late in the week. A system is 
expected to develop in the northern Great Plains Sunday into Monday, 
but high pressure will keep our region dry. The result will be 
increasing southerly flow and temperatures rising well into the
80s.
