SEVERE WEATHER FORECAST SYNOPSIS…ISSUED 9:35 A.M. EDT…APR. 06, 2016

For those who have donated to my site, your help has been greatly appreciated.  For those not aware, donations to my site help me offset my personal out of pocket expenses…such as some of the model maps you view on here, are only available due to my subscription to the corresponding site.  The F5 Data maps I post, also another out of pocket expense (monthly subscription).  Updates to software (weather related), and costs for my domain name are also out of pocket to me.  Any help you provide is immensely appreciated!  Although it may seem I am not here and working in support of your donation, I have to work my forecasting time around my ever changing work schedule.

Good day everyone!

The Storm Prediction Center (SPC) indicates a SLIGHT risk of Severe Thunderstorms for portions of MIDDLE TN…NERN MS…CENTRAL/NRN AL…NWRN GA…

A MARGINAL risk has been designated from PARTS OF LOWER OH VALLEY TO WRN MS…SRN AL AND CENTRAL GA….

…SUMMARY…
DAMAGING THUNDERSTORM WINDS WILL BE MOST PROBABLE ACROSS PARTS OF THE TENNESSEE VALLEY AND DEEP SOUTH IN THE LATE AFTERNOON TO EVENING. ISOLATED SEVERE GUSTS MAY OCCUR IN SURROUNDING AREAS FROM THE CENTRAL AND EASTERN GULF COASTAL PLAIN TO PARTS OF THE MID SOUTH AND OHIO VALLEY REGIONS.

SPC DAY 1 CONVECTIVE OUTLOOK

Based on analysis of the SPC outlook text, today’s threat pretty much repeats conditions seen yesterday…direr air/limited moisture over the risk area, moderate SBCAPE and MLCAPE values, etc.  Based on analysis of the early morning runs of both the RAP and NAM-WRF models using F5 DATA Severe Weather forecast software, surface dewpoints are forecast to only reach AOB 50F, with relative humidity once again AOB 50%.  Surface Based Convective Available Potential Energy (SBCAPE) and Mixed Layer Convective  Available Potential Energy (MLCAPE) values from the forecast soundings, are only forecast to average 500 j/kg, and the Lifted Index (LI) at -2.  The lack of strong instability and weak lift, should mean that any hail event should only produce small hail.  Based on the BRN (Bulk Richardson Number) index, supercell development should have a slim chance, but isolated supercells may not ruled out in the slightly more favorable environment in and just east of the risk area over MS.  Any supercells that develop, should be transient and brief, as the thermodynamics and kinematics are favoring more linear type storms.  Analysis of the forecast soundings DID NOT indicate any significant values to warrant concern for tornadoes, in which the SPC indicates >2% probability for tornadoes.  Based on a blend of the model solutions, forecast soundings currently indicate the following outlined area to have the best probability of experiencing severe thunderstorms.  Timing is pretty much close to yesterdays threat, in that the best chance of any severe weather should begin around late afternoon, and begin to wane just after sunset.

About palmharborforecastcenter

I am a Tropical Forecast meteorologist, providing hurricane forecasts during the Atlantic Hurricane Season. I retired from the U.S. Coast Guard in July of 2001. Meteorology became my passion in high school, and I have continued my educational background in meteorology since 1996, when I undertook the study of Tropical Meteorology. While working toward my degree, I had to unexpectedly withdraw from college due to my oldest sons medical reasons. I do however, meet the educational criteria of the AMS to be recognized as a meteorologist. Studies include, but are not limited to the Navy Aerographers Mate course, Naval METOC meteorology course, Meteorology 2010 Sophomore level course while attending St. Petersburg College, Clearwater, FL., Basic Forecasting course for operational meteorologists from Rapid WX, meteorology institute, a four month meteorological internship, and extensive research on numerous meteorological topics such as the MJO, NAO, satellite imagery interpretation, etc. I have been forecasting Tropical Weather (Tropical Storms and Hurricanes) since 1996, with my main client being three different Coast Guard Commands.
