- Seasonably cool into Wednesday, followed by a strong warming trend.

DISCUSSION

Issued at 219 PM EDT Tue Apr 7 2026

Canadian high pressure currently centered to our north will continue to extend into our area as it slides east through Wednesday. This high is providing dry and seasonably cool conditions. Patchy frost will be possible late tonight especially in normally colder outlying valley areas, with the highest chance for frost across the north. Temperatures in these locations will likely dip into the mid to upper 30s. and a few spots in the north will bottom out around freezing. Relative humidity values are low this afternoon and will be low again Wednesday afternoon, bottoming out in the 20s in most locations. High temperatures Wednesday will be close to normal for this time of year.

Heights will be rising Thursday and high pressure will continue to extend into the area. A few locations mainly north may see patchy frost again late Wed night, but after a chilly start Thursday temperatures in most valley locations will rise into the 70 to 75 range signaling the start of a strong warming trend. Temperatures are expected to climb well above normal by the Saturday through Tuesday time frame with most valley locations seeing highs in the lower to mid 80s. Relative humidity values will be low each afternoon at least into the weekend. Models generally agree that we will see the dry conditions continue through the weekend into early next week. However, some models show a weak and moisture starved cold front possibly making it far enough south to bring a few light showers to our northern areas around the Saturday time frame. However, right now this looks like a minority solution and the weekend is likely to stay dry. By Tuesday, a system approaching from the west may be close enough to bring a few showers or storms, but again the probability of precipitation looks quite low at this time.

AVIATION

(00Z TAFS) Issued at 729 PM EDT Tue Apr 7 2026

VFR conditions will prevail through the period. High pressure will move through, and east of, the region over the next 24 hours. Winds at KTYS and KTRI will be light and variable as a result. This pattern will likely produce SELY winds of 7-10kt at KCHA as the surface high influence creeps around the tail of the Appalachians and into the southern TN valley tomorrow morning.
