NWS Forecaster Discussion

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 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.
