. 06Z AVIATION UPDATE .

UPDATE. Issued at 922 PM CDT Sun Jun 20 2021

Cold front at 9 pm ran roughly from Dubuque through Cedar Rapids to Ottumwa. Ahead of this, scattered thunderstorms continue with a a potential for severe storms and a severe thunderstorm watch in place until roughly midnight. Behind the front, strong pressure rises were producing gusty northwest winds, gusting at as high as 30 to 40 mph. This will continue to advance southeast through the forecast area tonight and have updated the forecast for stronger northwest winds. By morning, the Canadian airmass will be in place over the entire area more comfortable dewpoints in the 50s.

SYNOPSIS. Issued at 330 PM CDT Sun Jun 20 2021

Back edge of stratiform light rain was finally moving into our eastern counties, with sunshine in our western counties. The cloud cover has kept afternoon temperatures in the 70s but with strong June sunshine this should push readings into the forecast highs in the 80s.

Meanwhile, deepening low pressure in southern MN has a cold front extending to northern KS, with a secondary cold front pushing across ND and nw MN. Pretty impressive front for mid June with north winds gusting to 40 mph in the northern Plains.

Strong thunderstorms were developing ahead of this front in south-central MN.

SPC mesoanalysis at 20z showed SBCAPE of 5000 J/kg in sw IA with effective bulk shear of 40-50 kt across northern IL, much of IA and southern MN. PWAT's were over 1.50 inches.

SHORT TERM. (This Evening through Monday) ISSUED AT 330 PM CDT Sun Jun 20 2021

Key messages:

1) SPC has an enhanced risk for severe storms this evening for portions of the area.

2) Time frame for severe weather is 6 pm to midnight.

3) Cooler and much lower humidity on gusty northwest winds Monday.

Tonight: CAM's indicates a few discrete supercells initially evolving into bowing segments ahead of strong cold front. Digging upper level trough providing large scale ascent, deepening cyclone and front pushing into an unstable, rich moisture warm sector should trigger severe storms. Golf ball size hail, damaging winds to 70 mph and a few tornadoes are all possible this evening. Cold front will sweep across the cwa overnight ending the storms and ushering cooler and less humid air on nw winds. Lows will range from the mid to upper 50s nw to the lower 60s se.

Monday: Delightful day with below normal temperatures and very comfortable humidity levels, due to northwest flow aloft and Canadian high pressure building into the area. Northwest winds should also be gusting to 30 mph, adding to a fall-like feel to the day. Highs will be in the upper 60s to lower 70s with dewpoints in the 40s!

LONG TERM. (Monday Night through Sunday) ISSUED AT 330 PM CDT Sun Jun 20 2021

Monday night: Clear and cool with light winds with high pressure ridge settling over the cwa. Lows will be in the mid 40s to around 50.

Tuesday: Another nice day with highs in the 70s but with light southwest winds.

Wednesday through Friday: High pressure shifts east with return flow of warm/moist airmass. Heights rise with zonal flow across the area. This pattern recognition in June suggests periodic rounds of thunderstorms, possibly severe, along with heavy rainfall. However, it is too early for details. Highs well into the 80s to near 90, with lows well into the 60s to lower 70s.

Next weekend: Cold front moves through with below normal temperatures and mainly dry weather. Highs near 80 with lows in the 50s to around 60.

AVIATION. (For the 06Z TAFS through 06Z Monday Night) ISSUED AT 1158 PM CDT Sun Jun 20 2021

Patchy low clouds and gusty northwest winds have moved into the area tonight in the wake of a strong cold front moving into northern Illinois. Brief periods of MVFR ceilings will be possible tonight, then VFR conditions will prevail Monday with mostly clear skies and gusty northwest winds becoming light by sunset.
