Area Forecast Discussion National Weather Service Green Bay WI 1043 PM CDT Fri Jun 30 2023 Updated aviation portion for 06Z TAF issuance .SHORT TERM...Tonight and Saturday Issued at 407 PM CDT Fri Jun 30 2023 Cumulus clouds should dissipate during the early evening hours, though middle and high clouds associated with the low pressure system over Illinois may remain across the southern third of the forecast area tonight. Drier air and light winds should allow for normal temperatures tonight. Saturday should be partly sunny and very warm with reasonably comfortable relative humidity. Lighter winds will permit a more significant lake breeze to form near Lake Michigan and keep the lakeshore cooler. Highs will range from 83 to 88 in most places, except in the 70s near the lakeshore. There is a slight chance that a shower or thunderstorm could form across the far Northeast corner of Wisconsin where there will be convergent lake and bay breeze boundaries. .LONG TERM...Saturday Night Through Friday Issued at 407 PM CDT Fri Jun 30 2023 Quiet conditions are expected through Monday before the pattern becomes active for the middle of next week, bringing the next chance for widespread precipitation. Very warm temperatures early next week with humid conditions on Tuesday, then cooler temperatures towards the end of next week. Saturday night through Monday...A weak cold front is forecast to drop south across the forecast area Saturday night, but a lack in moisture and overall forcing will hinder any precipitation from developing. Meanwhile, precipitation will be ongoing to the south of the forecast area associated with a shortwave trough. Anticipate the precipitation to remain south of the forecast area through Sunday. There still may be a small chance for an isolated shower to reach into the southern Fox Valley as the shortwave shifts east, but trends continue to keep the forecast area dry for Sunday. Surface ridging is expected to move over the area on Monday and cause winds to turn southwest, ushering in warmer, moist air. Temperatures will rise into the upper 80s to low 90s on Monday away from the lakeshore, with low 80s along the lakeshore. Rest of the extended...Models are still not in exact agreement with the timing of the cold front and precipitation for the midweek system. The current timing for the cold frontal passage and main axis of precip is Tuesday night through Wednesday night. However, there are also some indications for scattered WAA precip to develop ahead of the cold front sometime during the day on Tuesday. Despite there still being timing differences with the frontal passage, decided to include a mention of the shower and thunderstorm potential in the HWO with the holiday in mind. As for temperatures on Tuesday, with the southwest flow continuing to lift warmer air into the region, the combination of highs in the upper 80s and low 90s and dew points in the middle 60s, it will feel humid and slightly warmer than the air temperatures. Temperatures will then drop into the middle 70s to middle 80s on Wednesday. Dry and cooler conditions will follow the frontal passage on Thursday with below normal high temperatures mainly in the 70s. && .AVIATION...for 06Z TAF Issuance Issued at 1043 PM CDT Fri Jun 30 2023 VFR conditions are expected through the TAF period. Clouds will stream across from activity to the west and south, but do not expect anything other than scattered or broken middle and high clouds. Wind will be light to calm overnight, and increase to around 4 to 8 knots on Saturday. A lake breeze is likely to develop during the afternoon, changing the wind direction at eastern TAF sites (KMTW, KGRB, and KATW) from the NW to the E. Visibility will be good with no smoke concerns expected through the TAF period. && .GRB WATCHES/WARNINGS/ADVISORIES... None. && SHORT TERM.....RDM LONG TERM......Kruk AVIATION.......KLJ
