Area forecast discussion, May 25, 2:30 PM CDT, 37 minutes before
Area Forecast Discussion National Weather Service Nashville TN 230 PM CDT WED MAY 25 2016 .DISCUSSION... General trend into the weekend is for ML/UL long-wave like pattern to amplify as west coast trough develops into northern plains closed low by early Friday. Developing upper ridge somewhat dirty as moderate moisture remains as bits of weak energy pass. At LLs...high pressure holds but does show signs of weaken latter part of the week. Overall...isolated to scattered shwrs/storms are expected to continue into the weekend. Hard to put finger on exactly which day will have greater coverage without really any good organized features. But while pattern is not exactly summer like...is it similar as most activity is expected in the afternoons/eves as thermodynamic parameters pushing CAPE 2000-3000 range 18-03z time-frames each day. Early Sunday...upper ridge reacts to weak system heading up FL east coast as well as filling plains upper low. While upper ridging does hold, it dampens significantly and remains as such into the early part of next week. Despite weaker ridging, moisture source is more limited. Thus...isolated activity is expected in large part Monday-Wednesday...although Tuesday shwrs/strms may be a bit more numerous. Temps heading into the next week looking to remain well above normal. && .AVIATION... 18Z TAF DISCUSSION. BNA/CKV/CSV...Band of showers is moving across West Tennessee late this morning and appears to be picking up some steam. Latest HRRR also shows more widespread shower development during the afternoon, so will include TEMPO groups for light showers and VFR cigs at BNA & CKV. Expect generally benign weather after 00Z. At this time, radiation fog appears unlikely owing mainly to persistent VFR cigs. && .PRELIMINARY POINT TEMPS/POPS...
