Area forecast discussion...updated National Weather Service Jackson MS 924 PM CDT Friday Apr 17 2015 Update...expecting only slight chances for showers/storms overnight before better chances arrive tomorrow. Low temperatures tonight will be in the 60s. As for the current forecast...added patchy fog to the County Warning Area for later tonight into early tomorrow morning...and made minor changes to the hourly temperatures for this evening. /27/ && Aviation...expect a repeat of IFR category stratus and perhaps some fog later tonight persisting through early morning before mixing up to MVFR and eventually VFR category by early afternoon. Rain showers/thunderstorms and rain could become widespread by afternoon lasting into the evening with approaching shortwave trough...so expect a poor day for flying overall. /Ec/ && Previous discussion... /issued 500 PM CDT Friday Apr 17 2015/ Discussion...subsidence in the wake of overnight mesoscale convective vortex has kept convection at Bay for the majority of the afternoon and scoured out the higher dewpoints we have had the last few days. The exception has been a few storms in east MS along a left over convergent boundary in close proximity to nose of 300 mb 75 knot jet streak. While lapse rates are not that impressive at the moment...convective available potential energy around 2000 j/kg and 25-30 knots of deep layer shear could allow for a few storms to become strong. Shortwave ridging will allow for a quiet overnight once the evening convection subsides. Middle/upper level SW flow will crank back up early Saturday morning in advance of strong system moving out of The Rockies. Model data showing overnight convective area over the Upper Texas/la coast along marine layer boundary with stratiform precipitation beginning to enter the SW at dawn. Question Marks exist at present for severe potential Saturday. Presently...convective blob expected to develop and move east along the northern Gulf Coast overnight. If this slows down and stagnates along the MS/la coast...backing of low level wind field and advance of marine layer northward may not occur. Presently expecting the convection to continue racing easing east along its differential divergence bullseye. This will allow the atmosphere to reset quicker with backing low level winds and the marine layer boundary advancing northward during the afternoon. MLCAPES from 1500-2000 j/kg will pool along the boundary as it pushes north from S la/S MS...but lapse rates are nearly moist adiabatic in the deep tropical airmass (pw values near 2 in). Nevertheless...0-1 km srh values are ranging from 250-300 m2/s2 in close proximity to the boundary with low LCLs which should allow for the development of a few tornadoes. Some threat of wind as well from precipitation loading...but tornadoes and heavy rainfall are primarily expected. While the heavy rainfall risk will continue into the evening as the convective area moves NE...tornado risk will be diminishing with the loss of any remaining instability. /26/ Models for Sunday continue to support the risk for severe storms along with some potential for a higher end event. What is starting to become more clear is much of the day looks to be in a lull from convection after morning activity departs to the east and the round of storms will be more focused later between a 5pm to 3am window. In the wake of the Sat system...much steeper lapse rates will spread over the area (7.0 to 7.5 c/km)(29-31c vertical totals). Aloft much colder temperatures will move in with 500 mb readings of -15 to - 16c. This will all support SBCAPE of 2000-3000 j/kg as surface heating reaches around 80 degrees. This will all support vigorous storms with robust updrafts. Concurrent with this will be an overall drier atmosphere column as well with precipitable waters around 1.2 inches. This will lend to keeping storms more discrete along with an eastward deep layer (0-6km) shear vector of 40-50kts. Expectations are for not many (iso/sct) supercells that will pack quite the punch. Large hail > Golf Ball size appears very possible along with damaging winds which also could be higher end. Due to this possibility of seeing significant type weather (>2 in hail)...will up our outlook to sig over a decent portion of the northwest. Elsewhere the outlook will remain similar as storms may lose some potency as they push further east and get later into the overnight. /Cme/ && Preliminary point temps/pops...
