Daytime highs will range between five and fifteen degrees above normal. - Dry conditions prevail through this week, with the next chance for showers and storms not arriving until the weekend. && .SHORT TERM... Issued 318 PM CDT Sun Sep 15 2024 Tonight through Monday night: A few cumulus clouds developed this afternoon in the west where dewpoints didn`t quite mix out enough. Temperatures are around 80 near the lakeshore where there is an easterly wind component off the cooler lake, and upper 80s to around 90 in inland areas. Lows tonight will be in the lower 60s, similar to last night, with mostly clear skies. There is supposed to be an aurora event late tonight, so viewing should be ok if the cirrus can hold off or remain thin enough. Light winds and dewpoints in the lower 60s could allow for some patchy fog in low spots once again. Temperatures tomorrow will basically be a repeat of today. Mid and upper levels will be slightly drier than today as that upper ridge retrogrades a bit. Therefore, dewpoints should be a little cooler and diurnal cumulus clouds should be even more sparse. Monday night lows are forecast to be in the upper 50s to around 60. Cronce && .LONG TERM... Issued 318 PM CDT Sun Sep 15 2024 Tuesday through Sunday: Ridging and dry weather is going to hold over the eastern Great Lakes and Lake Michigan through at least Thursday night. We do not have any slight chance of rain in our forecast until early Friday morning and that is limited to west of Madison. Our extended forecast for next weekend brings in low chances (20 to 30 percent) of showers for Madison and west at times. There is low confidence for when the front will actually cross WI and that front may hold off until next week. Cronce && .AVIATION... Issued 318 PM CDT Sun Sep 15 2024 Patchy fog is possible in the typical low spots again tonight. Otherwise, expect VFR conditions to prevail due to dry air over the region. Diurnal cumulus clouds with bases of around 7000 ft are possible once again tomorrow. Cronce && .MARINE... Issued 318 PM CDT Sun Sep 15 2024 High pressure around 30.3 inches over the eastern Great Lakes and low pressure around 29.8 inches over the Plains will remain fairly stationary over the next several days. The high will weaken to 30.0 inches and the low will strengthen to 29.6 inches by Thursday. Winds over Lake Michigan will remain out of the south to southeast through this time, and generally be less than 15 kt. It is uncertain about when a front will move across Lake Michigan, but low pressure is expected to approach Wisconsin next weekend. Cronce && .MKX WATCHES/WARNINGS/ADVISORIES... WI...None.
