Updated aviation portion for 00Z TAF issuance
SHORT TERM. Tonight and Friday Issued at 239 PM CST Thu Mar 4 2021
Minimal changes made to the short term forecast as a surface high pressure will act to keep weather conditions mild and uneventful.
There were some low clouds across far east- central WI, mainly around MTW, early this afternoon, but those have since cleared out and skies were clear across all of central and northeast WI. Temperatures at 2 PM ranged from the lower 20s in northern Door Co, and in the low to middle 30s elsewhere.
A surface high pressure just north of WI will continue to drift slowly southward tonight and Friday, keeping skies mainly clear and winds light. Guidance shows there cloud be some scattered mid clouds overnight and into Friday, with a small wedge of moisture also noted in the models. Increased cloud cover a little bit from the previous forecast, but overall still expecting more stars/sun than clouds.
Overnight lows will be in the teens to low 20s. A few single digits are possible in the typical cold spots of north- central WI. Highs Friday will be a little warmer, in the upper 30s to middle 40s.
LONG TERM. Friday Night Through Thursday Issued at 239 PM CST Thu Mar 4 2021
Relatively quiet and mild conditions are expected for the weekend before a more active pattern sets up for next week. Eyes are still on a more significant system possibly bringing widespread rainfall to the area midweek. Temperatures are expected to remain above normal through this forecast period.
Friday night through Monday . Surface high pressure and a mean northwest upper-level flow will remain dominant over the region through Saturday night. This will keep conditions dry and mostly clear/sunny. The upper-level pattern will evolve as an upper-level ridge builds over the region into Sunday. Warmer air will be transported via south/southwest winds on Sunday allowing high temperatures to climb into the middle 40s to low 50s. Model guidance is still hinting at a weak surface cold front moving across the forecast area sometime Sunday night into Monday morning. Although the front appears to be moisture starved, there may be enough to squeeze out a few sprinkles. If anything, clouds are expected overnight into Monday morning. Little impact is expected to Monday's temperatures from the cold frontal passage. In fact, temperatures appear warmer on Monday with highs in the 50s.
Rest of the extended . Broad upper-level ridging and an increasing low-level south/southwesterly jet will arrive Tuesday ahead of a more significant system strengthening over the Central Plains. Models continue to struggle with a solution on the timing and placement of heaviest precipitation, however, there is some agreement with the forecast area being the warm sector. As of this forecast issuance, the forecast area could see around 0.50 to 1 inch of rain by Thursday.
AVIATION. for 00Z TAF Issuance Issued at 511 PM CST Thu Mar 4 2021
