Area forecast discussion, Jul 2, 3:14 PM CDT, 3 hours 30 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO 314 PM CDT Tue Jul 2 2013 .SHORT TERM...(This Evening through Thursday Night) Issued at 303 PM CDT TUE JUL 2 2013 Well developed mid-upper level circulation per water vapor imagery continues to drift southward through Iowa. Ahead of this feature, strong isolation has pushed temperatures into the lower 80s, generating 1000-1250 J/kg of CAPE despite dewpoints only in the low 50s. Recent upper air measurements show that this circulation has augmented the wind field, with a narrow corridor of 40 knot southerlies at 300mb. Through the balance of the afternoon and early evening, short-lived pulsed storms will build south from IA into northern MO. A few storms along the eastern flank of the upper circulation (NE MO) could become a bit more robust (small hail/gusty winds) due to the enhanced anvil exhaust. This feature, the primary vortex near St. Louis, and a third upper level trough over western Arkansas will do the Fujiwhara dance over the Show-Me state tomorrow, with models poorly representing the unique circulations as one expansive closed 576 height contour at 500mb. Expect fairly expansive Cu development by late morning, with scattered afternoon-eve convection across the CWA. Temperatures just a scoche cooler owing to broken cloud cover. 4th of July: Overall trends show the conglomerate circulation drifting west toward the Flint Hills, which should focus diurnal convection primarily over the Ozarks. Given the close proximity, still can't rule out isolated, brief showers/storms in the afternoon, but expect most of the region will be dry, with highs in the mid 80s and low humidity. .LONG TERM...(Friday through Tuesday) Issued at 303 PM CDT TUE JUL 2 2013 Friday through Tuesday... Large Rocky Mountain and western Atlantic ridges will block the pattern through the extended portions of the forecast. This will put the squeeze on the central US trough...eliminate it completely by Sunday or Monday as the western US ridge expands eastward. Models show dry conditions for most of the CWA through Sunday given the lack of upper vort max/cool pockets. Models show weak energy keeping the ridge from building into the CWA too strongly progressing through the cwa on Monday and Tuesday. This will bring a return to potential precipitation early next work week and keep temps in check. In a nutshell the extended will be mostly dry through the weekend with precip returning for Mon and Tues. Temps should remain at or below average values through the period. && .AVIATION...(For the 18Z TAFS through 18Z Wednesday Afternoon) Issued at 1231 PM CDT TUE JUL 2 2013 Well defined mid level circulation over IA quite evident on water vapor imagery, but not on other satellite channels. Downstream (south) of this feature, expect that VFR cumulus will readily develop over the next hour, spreading into NW MO during the afternoon. Forcing appears sufficient to drive at least widely scattered showers (perhaps a few thunderstorms) over this region later this afternoon, but coverage right now appears too limited to warrant inclusion in the TAFs. Winds will remain light from the north-northeast at 6-8 knots across the terminals this afternoon, becoming light and variable after 00Z. && .EAX WATCHES/WARNINGS/ADVISORIES... KS...NONE. MO...NONE. && SHORT TERM...Bookbinder LONG TERM...Bailey AVIATION...73
