(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus63 kmkx 212348 afdmkx area forecast discussion national weather service milwaukee sullivan wi 648 pm cdt Tue aug 21 2018 Update Few showers have developed from ketb to kryv, moving southeast as a result of passing short wave trof and density discontinuity. Should continue to affect southeast wi next several hours. MUCAPE around 500 j in the far southeast so isolated t possible next 1-2 hours. Aviation(00z tafs) Patchy MVFR ceilings associated with low level cold air advection to continue next several hours before ceilings lifting toVFR as drier air surges in. Prev discussion (issued 403 pm cdt Tue aug 21 2018) short term... tonight... Forecast confidence is medium. Light showers associated with low pressure exiting the area are moving out of southeast wi this afternoon. It is looking much less likely for another round of showers late this afternoon evening with a weak cold front dropping through. The hrrr and NAM models have backed off a lot and there is no sign up precip upstream. Winds will remain breezy out of the north-northwest. Expect clearing skies overnight as drier air works into the region. Temps will drop into the lower to mid 50s. Wednesday through Thursday... Forecast confidence is medium. Dry high pressure will take hold of southern wi on Wednesday and linger through Thursday. Cyclonic flow aloft will lead to diurnal cumulus clouds in southeast wi Wed afternoon. We will start to warm up again with southerly winds on Thursday. Long term... Friday through Saturday... Forecast confidence is medium. An upper low will swing through the upper midwest later in the week. It's expected to slide across southern wisconsin and bring us another round of rain. Precipitable water values will be around 1.6 to 1.8 again, so expect efficient rainfall and heavy rain is a possibility. Rain should begin in southern wi late Thu night and |
persist through Friday night. We will warm into the 80s for Saturday and Sunday. Sunday looks like a very warm and humid day. This will lead to instability, so there is a chance of storms by Sunday afternoon into the night. The better chance for strong storms will be to our north. Aviation(18z tafs)... the MVFR ceilings are slower to lift and clear than expected this afternoon. Look for skies to clear later than expected, but they should clear early Wednesday morning. Gusty north-northwest winds will persist through early evening and re-develop Wed afternoon. Expect diurnal cumulus clouds withVFR bases to develop late Wednesday morning. These may become broken ceilings for a time near lake michigan during the afternoon. Marine... gusty north-northwest winds will gradually diminish overnight. Waves will subside as winds become more off-shore. Timing for the small craft advisory still seems reasonable. Beaches... wind direction is marginal for a strong beach hazards statement since it is now becoming northwesterly rather than north. Given the lingering high waves, I will keep the beach hazards statement in effect for the overnight hours, but it is possible we could cancel it early (by early Wednesday morning). Mkx watches warnings advisories Wi... Beach hazards statement through Wednesday afternoon for wiz066- 071-072. Beach hazards statement until 6 am cdt Wednesday for wiz052-060. Lm...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
