Area forecast discussion, Aug 3, 12:31 PM CDT, 1 hour 12 minutes before
Area Forecast Discussion National Weather Service Springfield MO 1231 PM CDT Thu Aug 3 2017 ...18z Aviation Update... .SHORT TERM...(Today and tonight) Issued at 231 AM CDT Thu Aug 3 2017 A vigorous upper level shortwave over the Dakotas/Neb will move east with a trailing cold front beginning to move into our nw cwfa by early evening. Moderate instability just ahead of the front w/about 2000 j/kg mlcape and 20-25kts 0-6 km bulk shear would support some stronger updrafts this afternoon/evening before diurnal cooling occurs. The negative is a lack of overall sfc convergence, with winds already expected to be veered ahead of the sfc boundary. This may limit overall areal coverage and precip chances. SPC marginal risk over the nw cwfa looks good given the shear/thermo profile. Cooler/drier air lags the front a bit, but drier air will work it's way in overnight with north sfc winds. .LONG TERM...(Friday through Wednesday) Issued at 300 AM CDT Thu Aug 3 2017 This period looks unseasonably cool with global med range guidance showing an unusually deep upper level trough from the Plains to the northeast U.S. in one form or another. We will see periods of rain/showers/isolated thunder, but beyond early next week guidance varies quite a bit on rainfall amounts. Friday-early Saturday: Very cool temperatures will occur with sfc high pressure moving from the Plains, becoming centered over southern MO by the overnight hours/early Sat morning. Highs in 70s with low in the 50s to near 60 degrees, about 10-15 deg F below normal. Saturday afternoon-Sunday: Another system will approach from the west. Models have caught on to the ECMWF timing which begins to bring showers into the western cwfa by Sat afternoon with a subtle lead impulse. The main shortwave and sfc front/wave will move through Sunday. There will be some instability in place as the precip first moves in late Sat, but by and large storms will be harder to come by after the atmosphere gets worked over into Sunday. Will have to watch rainfall amounts, especially over the western cwfa Sat night into early Sunday with an increased low level jet and moisture advection. Could see general 1-3 inch amounts (highest over our western cwfa), but most areas are dry enough to take at least some rainfall. So at this point, only looking at minor/marginal overall flooding hazard threat (see WPC day three excessive rain graphic). We will continue to monitor fcst trends. Sunday night-Monday: A bit of break as Sunday's low center shifts east and the trailing front moves just off to the south. Some post frontal low clouds/fog may linger into Monday, especially over far southern MO. Tuesday-Wednesday: Have low confidence here, but 00z global models have backed off on precip amounts during this time. There is quite a difference in the timing of individual low amplitude shortwaves. Rain chances with a forecast blend are generally fairly low with some uptick possible by late Wednesday. && .AVIATION...(For the 18Z TAFS through 18Z Friday afternoon) Issued at 1231 PM CDT Thu Aug 3 2017 Generally, VFR conditions are expected through this TAF cycle. That being said, there will be a chance for isolated showers/T'storms through the afternoon and into the early evening hours as a cold frontal boundary moves through the area. This activity should remain rather isolated at best, however, locations that receive rain will experience some reduction in cigs/vis. Winds will shift from a westerly/southwesterly direction to a more northerly direction over time. This will signify the passage of the cold front due into southern Missouri by early evening/sunset timeframe. && .SGF WATCHES/WARNINGS/ADVISORIES... MO...NONE.
