000 FXUS63 KABR 151125 AAA AFDABR Area Forecast Discussion...UPDATED National Weather Service Aberdeen SD 525 AM CST Fri Nov 15 2019 .UPDATE... Issued at 523 AM CST Fri Nov 15 2019 See updated aviation discussion below. && .SHORT TERM...(Today through Saturday Afternoon) Issued at 333 AM CST Fri Nov 15 2019 For the most part low clouds/fog have failed to materialize with mostly high clouds and some low clouds confined to the upslope portion of the Coteau which the backdoor front has drifted up against. The rest of the CWA is under light southerly flow. As a system develops out west, low level flow becomes more easterly. This may still lead to some stratus development as an inversion strengthens across the CWA. In the interim, sunshine should at least still allow temperatures to warm back into the 40s. The front moving across the area Saturday still looks fairly unimpressive with just low POPs and little if any QPF. Frontal passage will at least help enhance mixing so despite cloud cover temperatures could at least still top out in the 40s. .LONG TERM...(Saturday Evening through Thursday) Issued at 333 AM CST Fri Nov 15 2019 The extended period will feature a few time periods where light rain or snow showers are possible. The most likely time periods of precipitation will be Saturday night, Sunday night into the day Monday, and late Tuesday night into the day Wednesday. The Saturday night system will be associated with a frontal boundary and upper level trough tracking across the area. The second system will also be with a frontal boundary moving through, but with much weaker upper level support. The third system will be precipitation on the north side of a low tracking across the central part of the country, also with just weak upper level support. These systems continue to look pretty weak, and do not anticipate much in the way of rainfall or snow accumulations with any of them. High pressure settles in over the area Wednesday night and Thursday, bringing dry and slightly cooler conditions. Temperatures will be fairly mild through the period, with highs in the mid 30s to upper 40s Sunday, in the 40s and 50s Monday and Tuesday, in the 30s and 40s Wednesday, and in the 30s on Thursday. Overnight lows will generally be in the 20s to lower 30s. && .AVIATION...(For the 12Z TAFS through 12Z Saturday Morning) Issued at 523 AM CST Fri Nov 15 2019 The far northeastern part of South Dakota and west central Minnesota will see some IFR cigs and vsbys in fog early this morning, with conditions improving after sunrise. Otherwise, VFR conditions will prevail across the area today and tonight. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...None. MN...None. && $$ SHORT TERM...Connelly LONG TERM...Parkin AVIATION...Parkin
