DISCUSSION

Issued at 248 AM EDT Sun Mar 22 2026

A low level SW flow will continue today as a low pressure system tracks from the central Plains to the lower OH Valley, tightening the pressure gradient across our area. Expect some gusty SW winds in the TN Valley, around 20-30 mph at times. Highs today will be well above normal - in the lower to mid 80s in most spots. This will be within a few degrees of record highs - the TRI record of 81 could be tied or broken, as well as OQT's record high of 83.

Tonight and Monday morning, a shortwave trough will move across the Great Lakes into the Mid-Atlantic region. The associated cold front will move across our area, but dynamics with upper trough and jet will be mainly north of the area. A line of weakening showers and a few elevated thunderstorms will move across southwest Virginia and northeast Tennessee between 2 and 8 AM. Main chances of rain will be north of interstate 40, with only light amounts between a tenth and a quarter inch.

A colder air mass will build into the area on Monday behind the cold frontal passage. High pressure over the Great Lakes and OH Valley region will promote drier and seasonally cooler conditions through Tuesday. By Wednesday, broad ridging will expand from the southwest with high pressure shifting eastward, leading to a return of southerly flow and warming temperatures. Rain chances return late in the week as a front settles somewhere in the TN/OH Valley region. The position of a large high pressure ridge across the Gulf Coast region will mean moisture will be limited, but the front could linger in the area for a few days as it remains nearly stationary and parallel to the midlevel flow.

AVIATION

(06Z TAFS) Issued at 134 AM EDT Sun Mar 22 2026

SWly gusts will increase during the day today ahead of a cold frontal passage Monday morning. Afternoon gusts may subside some around sunset, then increase again once the front nears from the north. Any sort of chance of precipitation from the front will most likely not fall during this TAF time period.
