Area Forecast Discussion National Weather Service La Crosse WI 312 PM CDT Thu Mar 21 2019 .SHORT TERM...(This evening through Friday) Issued at 312 PM CDT Thu Mar 21 2019 Latest water vapor satellite imagery indicates upper level trough over the eastern United States and upper level ridge on the lee-side of the Rocky Mountains. Latest 19z surface analysis shows surface ridge over western Iowa and southwest Minnesota. Subsidence underneath surface ridge is producing mostly sunny skies across the forecast area per latest visible satellite imagery. Tonight into Friday...the 21.12z GFS/NAM/ECMWF are in good agreement tracking a weak surface front south into the Ohio River Valley. The models are suggesting cool air advecting into the area after 06z Friday with 925mb temperatures falling to -2 to -5 degrees celsius. Temperatures are expected to be below normal with highs mainly in the middle 30s to 40s. .LONG TERM...(Friday night through Thursday) Issued at 312 PM CDT Thu Mar 21 2019 Upper level ridge builds into the Upper Midwest Friday night into Saturday and the forecast area will remain dry and slightly warmer than normal Saturday. Upper level trough breaks ridge down Saturday night into Sunday. Pieces of energy ejects out of the trough and into the Upper Midwest. The 21.12z GFS/NAM indicate weak isentropic lift at 295k surface and 850-700mb layer QG forcing mainly over the southern forecast area in association with the pieces of energy. Drier airmass over the northern portions may delay the precipitation onset...and the higher likelihood of rain will occur over the southern forecast with the possibility of rain or snow over the northern portions of the forecast area. Main forecast concerns Sunday night through Thursday are precipitation chances Sunday night and Wednesday into Thursday. The 21.12z GFS/ECMWF/GEM are in good agreement digging upper level trough over the northeast United States into early next week...then build shortwave ridge into the Upper Midwest and Great Lakes Region Wednesday into Thursday. Weakening impulse slowly moves into the Ohio River Valley Sunday into Monday. Forecast area on northern periphery of surface low/upper level features and will spread light rain or snow across much of the forecast area Sunday night. Shortwave ridge builds into the Upper Midwest and Great Lakes Region and allows dry weather with warmer air advecting into the forecast area. The 21.12z 925mb temperatures warm to plus 6 to plus 10 degrees celsius. High temperatures are expected to climb into the 50s by middle of next week. The 21.12z GFS/ECMWF/GEM suggest shortwave ridge breaks down and track upper level trough into the Northern/High Plain states Thursday. However...models diverge on placement/timing of the upper level trough. At this time...will leave mention of precipitation chances across forecast area...based on the timing/placement issues of the upper level trough. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1231 PM CDT Thu Mar 21 2019 Main concerns through taf period are winds this afternoon. A weak surface front over northern Minnesota will push south into northern Iowa tonight. Gradient will tighten along with mixing of winds aloft to surface will allow winds to remain around 10 knots with gusts up to around 20 knots this afternoon at RST/LSE taf sites. Moisture is lacking with surface front...expect a few to scattered clouds at both RST/LSE taf sites through taf period. VFR conditions will continue to prevail. && .ARX WATCHES/WARNINGS/ADVISORIES...
