DISCUSSION

Issued at 1137 PM CST Fri Nov 6 2026

Tonight

A shortwave trough will move southeast along the US/Canadian border tonight. Soundings show that the air mass over the area is very dry below 20K feet. It is interesting that the soundings show that the air mass between 500 and 300 mb has lapse rates over 8C/km. This could result in some virga well aloft. Low temperatures will range from the lower 30s to lower 40s.

Sunday through Tuesday

High pressure will provide dry weather through this period. As the winds become more southerly with time, temperatures will gradually warm. High temperatures will be in the 50s on Sunday and Tuesday and range from the mid-50s to lower 60s on Monday. Low temperatures will range from the mid-20s to mid-30s Sunday night and be in the 30s and 40s for Monday and Tuesday nights.

Wednesday into Friday

A Canadian cold front will move southeast through the area on Wednesday afternoon/night. This might bring some small chances of accumulating precipitation to the Midwest, but confidence was too low to include in the forecast at this time.

As the long-wave upper level ridge amplifies to the west from Thursday into Friday, a long-wave trough will develop along and east of the Mississippi River. The coldest air continues to look to be over New England and the eastern Great Lakes.

High temperatures will be in the 40s and 50s on Wednesday and in the 40s for Thursday and Friday. Low temperatures will be in the 30s on Wednesday and range from the mid-20s to mid-30s on Thursday and Friday nights.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1142 AM CST Sat Nov 7 2026

While VFR conditions are likely (70%) to prevail over the next 24 hours, there is some indication that a clouds in the 800-1500 foot layer may develop this evening ahead of an advancing front. Have therefore retained the non-ceiling mentions of MVFR height clouds from the previous TAF with some adjustments to timing. Arrival of the front should lead to drier conditions and dissipating clouds, should they develop. Winds this afternoon will be out of the southwest to around 15 knots and will become out of the northwest early Sunday after the aforementioned front arrives. Wind profiles in the lower atmosphere suggest valley fog/stratus will not recur early Sunday.
