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.
