Updated aviation portion for 00Z TAF issuance

SYNOPSIS. Issued at 145 PM CST Fri Mar 5 2021

An amplified mean flow consisting of an eastern Pacific upper trough, Rockies upper ridge and eastern NOAM upper trough is forecast to transition eastward this weekend with the upper ridge moving into the Great Lakes. In response, temperatures will make a leap into well-above normal territory during the Monday-Wednesday time frame. By the middle of next week, the Pacific upper trough will have moved into the western CONUS with a piece of energy ejected northeast into the western Great Lakes, while a cold front moves through WI. We should see increasing chances for precipitation by Tuesday night into Wednesday night. A second piece of energy and surface wave on the front could bring more precipitation chances Thursday night into Friday.

SHORT TERM. Tonight and Saturday Issued at 145 PM CST Fri Mar 5 2021

Tonight through Sunday

A surface ridge axis will stretch from western Ontario south- southwest all the way to TX through Saturday, keeping a dry and seasonably cool temperature regime over northeast WI on north- northwest winds. Time sections show some passing middle and high clouds at times, thus mostly clear to partly cloudy skies should suffice. Min temperatures tonight to range from 5 to 10 above zero north-central WI, to around 20 degrees east-central WI. Max temperatures Saturday to be in the middle to upper 30s north- central WI/near Lake MI, lower to middle 40s central/east-central WI.

The ridge axis slides toward the eastern Great Lakes region later into the weekend, allowing for a return flow to set-up over WI. Southerly winds will increase on Sunday, between the retreating high pressure and an area of low pressure located well north in Canada. Models do show a weak shortwave trough that will reach WI late on Sunday. A lack of moisture would preclude any mention of precipitation, but we should see a gradual increase in clouds. Min temperatures to again have quite the range from the single digits above zero near the MI border where a snowpack exists, to around 20 degrees east-central WI. Max temperatures on Sunday to reach the middle to upper 30s near Lake MI, lower to middle 40s north and middle 40s to around 50 degrees central/east-central WI.

LONG TERM. Saturday Night Through Friday Issued at 145 PM CST Fri Mar 5 2021

Sunday night through Friday

Some clouds may linger over the forecast area into Sunday night as the shortwave trough gradually shifts to our east. A weaker surface ridge is then expected to move across WI on Monday with more sunshine and warmer temperatures. A somewhat flat upper ridge to also be over WI with 8H temperatures rising to around +4C. Max temperatures for Monday will range from the upper 40s to lower 50s near Lake MI, lower to middle 50s north and middle to around 60 degrees central/east-central WI.

Both the surface and upper-level ridges shift to the east Monday night, backing winds to the southwest once again. A modest push of WAA may bring a few more clouds to the area, especially by Tuesday afternoon. Nevertheless, 8h temperatures of +4 to +6C should allow max temperatures on Tuesday to soar into the middle 50s to lower 60s over most of northeast WI. The exception would be near Lake MI where a touch of an onshore component to the winds will keep temperatures in the upper 40s to middle 50s.

Our first real precipitation chance arrives Tuesday night as a cold front moves across the Upper MS Valley and a piece of energy from the West Coast upper trough lifts northeast into the central Plains. This front moves into WI on Wednesday and will be the main focus for additional precipitation chances. Models have slight differences with respect to timing of the front and location of where heavier rains would fall. Thunder cannot be ruled out either Wednesday afternoon. Max temperatures for Wednesday will cool a bit due to clouds/precipitation, thus readings to be around 50 degrees north/lakeside, middle to upper 50s central/east-central WI.

Precipitation chances would continue into Wednesday night as the front continues to move through the area. Precipitation type would still be rain as cooler air lags behind the front. A weak area of high pressure to build into the region for Thursday, allowing for some mixed sunshine to return. Max temperatures on Thursday to range from the middle 40s north-central, to the lower 50s west of the Fox Valley.

Clouds and a chance of precipitation may return for Thursday night into Friday morning as some models bring a surface wave that will ride northeast along the old cold front situated over northern Wl. Higher pops placed over central/east-central WI, while northern WI may stay dry through most of the event. The front is forecast to sage far enough south by Friday afternoon to end the precipitation threat. Precipitation type may be an issue Thursday night as colder air settles over the region, but it is way too early to make this determination. Max temperatures for next Friday to be in the lower 40s north-central/Door County, middle to upper 40s elsewhere.

AVIATION. for 00Z TAF Issuance Issued at 530 PM CST Fri Mar 5 2021

A surface ridge axis is expected to stretch from western Ontario through Wisconsin to Texas over the next 24 hours. Thus, good flying conditions are expected with only some passing high clouds at times. There could be a little patchy fog over central Wisconsin toward daybreak as melting snow adds moisture to the air. However, not enough confidence to add to any of the TAF sites at this time.

GRB WATCHES/WARNINGS/ADVISORIES. NONE.
