LATEST UPDATE . Aviation

SYNOPSIS. Issued at 329 AM EST Mon Mar 8 2021

- Dry and warmer today and Tuesday

- Potential for fog/freezing fog tonight

- Wet Wednesday night and Thursday

DISCUSSION. (Today through next Sunday) Issued at 329 AM EST Mon Mar 8 2021

-- Dry and warmer today and Tuesday --

Latest IR loop shows some mid cloud moving across Lake Michigan in association with a short wave cross the Great Lakes. It'll take several hours for these clouds to move through, so we're likely looking at a partly sunny day. Southwest flow will increase today and Tuesday bringing warmer air to much of the CWA. The exception will be the lakeshore where flow off of the cold lake will hold temperatures in the 40s. Elsewhere, the temperature will climb into the lower to mid 50s north of I-96 and upper 50s to near 60 south of I-96 today.

-- Potential for fog/freezing fog tonight --

The southwest flow will bring an increase in low level moisture. The upper ridge moving over the state tonight will result in light winds. The combination of those two will likely result in and increase in clouds and fog tonight. The ECMWF seems to have a pretty good handle and is close to CONSShort and points toward dewpoints remaining in the lower to mid 30s tonight and temperatures fall close to the dewpoints. We're likely to see fog develop and perhaps freezing fog, especially north of I-96. If this occurs, some roads could become slick Tuesday morning.

HREF indicates the clouds will decrease Tuesday afternoon and that will help temperatures to climb into the lower 60s south of I-96 and upper 50s north of there. Of course, the lake shore will be colder.

-- Wet Wednesday night and Thursday --

Low pressure moving northeast along a cold front will push rain through Wisconsin and the northwest CWA Wednesday. The rest of the CWA will see rain Wednesday night and Thursday. The latest trend of the models lingers the frontal boundary over southern Lower Thursday which means we may see heavier rain along/south of I-94. The GFS and ECMWF both show around a half inch of rain in that area Thursday. High pressure will build into the CWA Thursday night and Friday and we should dry out then.

AVIATION. (For the 12Z TAFS through 12Z Tuesday morning) Issued at 652 AM EST Mon Mar 8 2021

Gusty southwest winds to 30 kts expected today as VFR continues with cloud bases at or above 8000 ft. Winds quickly diminishing this evening, then some fog and/or low stratus potentially developing after midnight tonight.

Confidence is currently low as to the extent of any fog/freezing fog late tonight, but potential does exist for some LIFR vsbys to be present at 12Z Tuesday. For now went with 2 mile IFR vsbys late tonight in the TAFS but this will need monitored.

MARINE. Issued at 329 AM EST Mon Mar 8 2021

We extended the Small Craft Advisory through this afternoon due to winds taking a bit longer to diminish. We may need another SCA Wednesday into Thursday ahead of the next system.

GRR WATCHES/WARNINGS/ADVISORIES. MI . None. LM . Small Craft Advisory until 4 PM EST this afternoon for LMZ844>849.
