Updated aviation portion for 18Z TAF issuance
SHORT TERM. Today . Tonight . and Saturday Issued at 403 AM CST Fri Mar 5 2021
Quiet weather will continue through the short-term portion of the forecast.
A surface ridge will linger across northeast Wisconsin today through Saturday, keeping dry conditions in place. Aloft, the area will continue to be on the inflection point of troughing to the east and ridging to the west. This will keep northwesterly flow through much of this time period. There will be occasional passing clouds as mid- level moisture brushes through the area from time to time, specifically, this morning and again overnight into early Friday morning. Not expecting a solid deck of clouds; rather, a few locations may see broken cloud cover for a brief period of time. High temperatures are forecast to be in the upper 30s to mid 40s. Overnight lows are expected to drop into the teens for much of the area; however, a few single digits will be possible across the Northwoods.
LONG TERM. Saturday Night Through Thursday Issued at 403 AM CST Fri Mar 5 2021
A surface high pressure ridge over the Midwest will shift east this weekend and generate a southerly flow from Texas to the Great Lakes. Temperatures will become warmer in Northeast WI in response to this change and remain above normal through the long term period. On Tuesday, low pressure will begin to develop over the Plains States and along the front range of the Rockies. This area of low pressure will spread northeast and bring a chance of precipitation to our area on Wednesday and Thursday.
AVIATION. for 18Z TAF Issuance Issued at 1126 AM 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.
