Area Forecast Discussion National Weather Service La Crosse WI 133 PM CDT Thu Jul 4 2019 .SHORT TERM...(Tonight through Friday Night) Issued at 133 PM CDT Thu Jul 4 2019 GOES water vapor imagery and RAP 500mb analysis showing a weak mid- level shortwave trough rotating through eastern MN. So far, convection has been somewhat limited with this feature. Latest CAMs very consistent in forming scattered showers and thunderstorms along and ahead of this feature -moving through the area this evening and exiting east by midnight. So, will the fireworks be a washout for tonight? Appears most susceptible area will be along/east of the Mississippi River according to CAMs consensus. There will also be a marginal risk of strong to severe storms as there is plenty of cape (3500-4800J/kg 0-3km mucape), but shear is lacking for organization. Could see some isolated dime to quarter size hail along with potentially damaging microburst. Otherwise, lightning and heavy downpours would be the main impacts. Southwesterly aloft continues Friday, bringing another packet of weakening PV-advection and MCV into the area by late in the afternoon into Friday evening. This will likely trigger additional scattered showers and thunderstorms during peak heating with pv forcing possibly continuing the convection into the overnight hours. Otherwise, plan on highs Friday in the 80s with overnight lows in the 60s. .LONG TERM...(Saturday through Thursday) Issued at 133 PM CDT Thu Jul 4 2019 Slightly drier/cooler air filters into the area for Saturday with highs in the upper 70s/lower 80s and dewpoints in the mid 50s to lower 60s. The NAM has some morning convection but then drying out for the afternoon. However, the GFS and ECMWF linger convection through the entire day. Hopefully, the NAM turns out to be correct as we could use some drying out. Upper level ridge amplifies over the central conus and builds east into the Upper Mississippi River Valley Sunday into Monday. But, as it builds in, there are indications of a weak trough rounding the ridge and producing a few showers and storms -with southern MN/northeast IA/far southwest WI most susceptible. Otherwise, pleasant temperatures and dewpoints are expected. Highs both days look to be in the upper 70s to lower 80s with dewpoints in the 50s/60s. Upper level ridging shifts east Tuesday with a significant trough and surface cold front pushing through Tuesday night into Wednesday. This will likely stir up more showers and storms for the area. Temperatures are expected to be right around seasonable norms. Ridge rebuilds over the area Thursday for some drying, or that is decreasing rain activity. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1135 AM CDT Thu Jul 4 2019 Cigs: variable mostly bkn decks through the afternoon into early evening. Expected to stay VFR for now, but can't rule out a few hour drop into MVFR if west-east line of storms develop across TAF sites. Generally high sct-bkn clouds later tonight. WX/vsby: meso models remain in good agreement with firing bkn-sct line of shra/ts in the 21-23z time frame, along a sfc boundary and south of weak sfc low/upper level shortwave. The west-east line could setup along or just south of the I-90 corridor per these short term models. For now, will cover potential with VCTS...updating if likelihood/confidence for impacts at KLSE/KRST increase. Storms should move east/diminish with loss of heating by 02-03z. Any rain will add to the already relatively high moisture content of the near sfc layer. Couple this with a light and fairly deep wind layer and the potential for at least some mvfr br is on the increase. KLSE looks a bit more like a valley fog event - with some potential to drop sub 1sm. Climatologically not the time of the year, but winds and T/Td spreads are favorable. Will cover KLSE with BCFG for now and MVFR BR at KRST. Winds: south becoming mostly westerly by the evening...and then generally light and variable through the night. Looks to stay light but a bit more east Fri morning. && .ARX WATCHES/WARNINGS/ADVISORIES... WI...None. MN...None. IA...None. && SHORT TERM...DAS LONG TERM...DAS AVIATION...RIECK
