Area forecast discussion, Mar 29, 6:29 PM CDT, 32 minutes before
Area Forecast Discussion National Weather Service Topeka KS 629 PM CDT Wed Mar 29 2017 ...Update to aviation forecast discussion... .SHORT TERM...(This evening through Thursday) Issued at 131 PM CDT Wed Mar 29 2017 Main focus in the short term will be the potential for a few strong to severe storms this afternoon across east central Kansas, where a few patches of sun have brought MUCAPEs up to around 500 J/kg, and deep layer shear remains around 60 kts. The window for any strong storms will be short as the surface low now near ICT lifts northeast, dragging a cold front through the remainder of the forecast area by early this evening and sweeping any robust deep convection out of the area. Storms are developing now and with limited instability may take a bit to get going, but will bear watching over the next several hours as they push northeast across southeastern portions of the forecast area. Low-level shear and helicities are quite strong, so main concerns with any strong, organized convection will be hail and perhaps an isolated tornado. Stratus and rain showers will follow behind on the northwest side of the low, and will linger through the overnight and into midday Thursday before exiting off to the east. .LONG TERM...(Thursday night through Wednesday) Issued at 131 PM CDT Wed Mar 29 2017 A brief lull in precipitation is expected Thursday night through Friday as shortwave ridging builds over the region, then another wave in the stream of disturbances slides across the southern CONUS this weekend through early in the work week, bringing precipitation chances Saturday and Sunday. Have added some isolated thunder on Saturday afternoon and evening, but the track of the surface low will be far enough south that most instability will focus mainly south of the CWA. Another low will follow in its wake Wednesday and Thursday with another very similar track, bringing a brief dry period Monday, then rain chances Tuesday through the end of the forecast period. Severe weather potential will depend on the track of each of these surface lows and their associated boundaries, but at this time appears to be focused more to the south of the forecast area. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 627 PM CDT Wed Mar 29 2017 Kept TAFs on the more pessimistic side as low clouds and prevailing rain lie not far west of the terminals. Kept better cigs for a few hours at TOP/FOE before IFR spreads back eastward. Anticipate rain will prevail till near the noon hour tomorrow. && .TOP WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...Laflin LONG TERM...Laflin AVIATION...67
