Area forecast discussion, Jun 15, 6:10 PM CDT, 2 hours 4 minutes before
Area Forecast Discussion National Weather Service Hastings NE 610 PM CDT Thu Jun 15 2017 .SHORT TERM...(This evening through Friday) Issued at 151 PM CDT Thu Jun 15 2017 Convection is rapidly firing along an old frontal boundary and area of convergence across north central Kansas this afternoon. While this activity is mainly limited to a few severe storms just south of our forecast area...continue to expect additional development over the next several hours to potentially spread into our southern tier of Kansas counties...across Rooks...Osborne and eventually Mitchell counties. While some model data tries to take this just a bit further north...latest short term solutions from the HRRR/RAP are tracking storms more eastward...so how far north things eventually spread is somewhat questionable. Evenso...could not justify removing chances for thunderstorms through the early evening hours across portions of south central Nebraska...despite this area most likely remaining dry this evening. Expect the threat for severe weather across our Kansas counties to end fairly rapidly during the early evening hours as this afternoons activity continues to push further south and east. Models have been pretty consistent with this...and did trim pops during the evening hours and removed them for the overnight periods as a result. With some clouds around overnight...and a shift in the winds to a more southerly direction...expect a fairly mild night across the area...and did increase overnight lows a couple of degrees in spots. Otherwise...expect thunderstorm chances to return by Friday afternoon as good surface heating should help to erode the CAP across the area by late afternoon...with a nice gradient in dewpoints likely becoming the focus for some strong to severe thunderstorms late in the day. This dry-line is a bit further east by peak heating time than it was yesterday at this time...but continue to think there will be at least a chance of storms across much of the area during the late afternoon hours...with chances focused across our southeastern third of counties by early evening. .LONG TERM...(Friday night through Thursday) Issued at 151 PM CDT Thu Jun 15 2017 Expect a fairly strong cold front to race south across the local area on Saturday...with the timing of this front key to how much convection we see across the area Saturday. The latest run of the NAM already has this front to the NE/KS state line by 18Z Saturday...which could limit severe potential across the local area late in the day. Evenso...should see some thunderstorm activity develop across the high plains and advect across portions of the area during the late afternoon through evening hours. Expect a return to near normal temps behind the aforementioned front on Sunday...which combined with steady northerly breezes... should make for a very nice afternoon. Thereafter...dry weather is forecast through at least Tuesday afternoon...when a small chance of thunderstorms returns to the local area with weak disturbances rolling off the high plains late Tuesday and again late Wednesday. These look like pretty iffy chances for thunderstorms at the current time. Temperature wise...with high pressure spreading its influence across the local area by early next week...expect above normal temps to return next Monday through at least Thursday of next week. && .AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Friday) Issued at 554 PM CDT Thu Jun 15 2017 Showers and a few thunderstorms which developed southeast of the terminals late this afternoon have diminished and dry weather is forecast through the night. A frontal boundary crossing the terminals Friday afternoon/evening will bring small chances of storms however chances do not appear great enough to insert in TAFS with the better chances southeast of KEAR and KGRI. Wind speeds will remain light with clouds at VFR levels. && .GID WATCHES/WARNINGS/ADVISORIES... NE...None. KS...None. && SHORT TERM...Rossi LONG TERM...Rossi AVIATION...Fay
