Area forecast discussion, Nov 14, 6:21 PM EST, 1 hour 5 minutes before
area forecast discussion national weather service louisville ky 621 pm est mon nov 14 2011 ...Mesoscale update... Updated the next couple of hours' worth of grids to reflect the line of storms just now beginning to penetrate the cwa in southern indiana. For the remainder of tonight, the main threat appears to be damaging winds, hail, and the possibility of an isolated tornado but the latter hazardous weather should remain in Southern Indiana and north-central Kentucky. && .Short term (this evening through tuesday)... ...Strong to severe storms possible this evening/moderate to heavy rain overnight... Surface wave associated with the right entrance region of an upper level jet will move from central Illinois to north central Indiana this evening along a nearly stationary frontal boundary. Tornadic storms have already fired just ahead of this boundary from east Central Illinois to north central Indiana. The broken line of storms will gradually sink south through the late afternoon and early evening with storm motion from wsw to ene along the line. At this point, the best time frame for the line and clusters of storms ahead of the line into Southern Indiana and along the Ohio River would be from 7 pm to midnight est. Thereafter, broken line of storms/quasi-linear structures should sink south of the ohio river into north central Kentucky and make progress into the blue grass. Latest laps soundings still show a weakly capped environment over the forecast area, however this should not last long as narrow axis of low 60s dew points and steeper mid level lapse rates move in over the next few hours. Forecast soundings for later this evening are quite impressive with strong speed shear sufficient for supercells and bowing segments, and dry mid level air that would support a damaging wind threat. Surface based instability should be on the order of 500 to 1000 j/kg across S. Indiana/N Central Kentucky, although if storms arrive toward the end of the time frame offered above, storms will likely be slightly more elevated. With the timing of storms more toward the evening, like that the biggest tornado threat is to the north of the Ohio river, with more of a damaging wind threat from broken line segments into our area. A few splitting supercells cannot be ruled out through the evening. As we move into the overnight hours, column saturates with pwats increasing to 1" - 1.5" through the column. This will support a heavy rain/flash flooding threat, especially with storm movement parallel to the mid level flow/training. The most likely area to experience 1" to locally 2" of rainfall will be along and just south of the i 64 corridor overnight. Have kept low temperatures for the overnight on the high side of guidance with mild dew points in the region and heavy sky cover. As front sinks south of the Ohio river toward dawn, Southern Indiana could see the low to mid 50s. Elsewhere south of this line, mid to upper 50s are anticipated with perhaps a low 60 reading in the lake cumberland region. As we move into daybreak on tuesday, frontal boundary will stay parallel to the mid level flow and stalled over the center of our cwa. This will keep steady rain and scattered thunderstorms ongoing through the whole day. An additional 0.5" - 1" amounts will be possible. The mercury will not move a whole lot tomorrow with highs only in the upper 50s to low 60s. .Long term (Tuesday night - Monday)... Low pressure will spin up over Texas Tuesday and move northeast up the surface boundary into the Tennessee Valley Wednesday morning, and off to New England by Wednesday evening. Plenty of moisture will accompany this wave and widespread showers are expected tuesday night into wednesday morning, decreasing Wednesday afternoon as the wave moves quickly away. During the tuesday night-wednesday time period it looks like qpf amounts of 1 to 2.5 inches will be possible in Kentucky, with 0.5 to 1 inch amounts in southern indiana. Embedded rumbles of thunder will be possible tuesday night, but this will be more of a heavy rain scenario than a severe scenario. High pressure will move in from the west and across the region behind the departing storm system, providing us with dry pleasant weather wednesday night through at least friday night. The coolest temperatures will come wednesday night and thursday night with lows in the upper 20s to lower 30s, and highs thursday around 50, or about 10 degrees below normal. Temps will then begin to moderate heading into the weekend ahead of the next approaching storm system. A plains storm system will get itself together friday night and saturday and head east into the ohio valley sunday. After a brief break sunday night another red river valley wave may develop and move northeast into our neck of the woods on monday. The 00z model runs brought precip into the lmk cwa as early as saturday, however the cold front won't arrive until sunday, the 12z gfs keeps precip off to our west on saturday, and general model behavior lately has been to steadily slow systems down in their solutions. So, will keep any pops saturday quite low, and will reserve higher pops for saturday night into sunday with the passage of the cold front. Will continue pops into monday as that southern wave brings more showers into the area. && .Aviation (00z taf issuance)... Well...through 00z the main issue will be gusty s-swly winds of 15 to 25 mph range with gusts to 30 mph range. These will be slacken to 10-20 range thereafter with some gusts up to 25...with higher gusts in convection. Sct strong to severe storms have developed across se mo and srn il and are rapidly move e-ne and beginning to merge with the initial line of the storms over Central IL/IN. These storms will affect sdf 1st between 8 pm to 11 pm est time frame. LEX's threat should be more in the 930 pm to 1230 am est. BWG's svr threat is minimal and would be after midnight. The main threat will be strong damaging winds. Overnight the frontal boundary will stall out across the area...bringing a moderate rain threat with prevailing low mvfr conditions and occasional ifr conditions. Intermittent rain showers and a few thunderstorms will be possible during the day on tuesday as the frontal boundary remains over the area. && .Lmk watches/warnings/advisories... In...none.
