NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Jackson Kentucky 
344 am EDT Tuesday Jun 30 2015 


Update... 
issued at 150 am EDT Tuesday Jun 30 2015 


Showers and thunderstorms have exited the area. However still 
seeing an area of weakening light echos across our far south. 
This light rain should dissipate over the next hour. Hrrr still 
showing the potential of an isolated pop up here and there through 
the remainder of the overnight. Also still seeing an occasional 
pop up here and there across the region in the regional mosaic. 
Therefore saw no reason not to keep a slight pop through dawn. 
Grids have been brought in line with hourly trends. No other 
changes to the forecast package. 


Update issued at 835 PM EDT Monday Jun 29 2015 


Cold pool has pushed to the south...and storms have been on the 
decline in general as we lose instability. A few storms are 
hanging on near and north of the Ohio River...however these look 
like they will weaken before clipping our northern most 
locations. The Tornado Watch will expire on time at 9 PM. Will 
update the zones and grids at that time. Fog will also need to be 
beefed up...with debris clouds likely thinning through the 
overnight and winds going light. 


&& 


Short term...(this evening through Tuesday night) 
issued at 400 PM EDT Monday Jun 29 2015 


Amplified pattern remains in place with sharp ridging across the 
western Continental U.S....while troughing dominates across the eastern 
Continental U.S.. a short wave trough is currently moving through the Ohio 
Valley...with a weaker surface reflection of a low currently 
located near central Indiana...and a sheared out cool front 
dangled southwest towards the bootheel of Missouri. Scattered to 
numerous showers and storms have broken out across mainly the 
western half of Kentucky this afternoon...with some scattered 
cells making it into eastern Kentucky in the past hour. 


Cape and shear are meager this afternoon across our area...however 
a few storms may reach severe limits. The best low level shear 
remains north of I-64...so think that the tornado threat for our 
area is low...but will keep an eye on any longer-lived cells that 
manage to sustain themselves out of north central Kentucky. 


Expect the activity to wane this evening as we lose heating and 
the short wave exits. Temperatures will not be as pleasant as last 
night...with lows in the low to middle 60s and some patchy fog 
around. 


Tuesday will feature another day of mainly afternoon convection as 
another short wave trough rotates through the area. A few storms 
may get on the strong-side...with perhaps a bit better 
instability...although shear looks meager once again. Convection 
will once again diminish Tuesday night as we lose heating and some 
modest short wave ridging ensues. Lows will be similar to tonight in 
the low to middle 60s...with patchy fog around once again. 


Long term...(wednesday night through monday) 
issued at 344 am EDT Tuesday Jun 30 2015 


Long range models are still in very good agreement starting out 
Thursday with a deep longwave troughing pattern setting up across 
much of the eastern Continental U.S. And remaining in place through much of the 
weekend...while slowly dampening. This pull of northerly air will 
keep temperatures below normal through the weekend as well. 
Multiple shortwaves will traverse the longwave trough...which will 
likely affect much of the Ohio River valley...bringing enhanced 
areas of lift for showers and thunderstorms...and even some mesoscale convective system 
potential. A strong upper level low will gain strength as it moves 
south into southern Canada Sunday into Monday. This will dampen the 
trough across the eastern Continental U.S....but will keep a weak northwest flow 
regime across the Ohio River valley. The upper level low will then 
shift eastward Monday night into Tuesday...directly impacting the 
upper Great Lakes. Expect energy from this system to impact as far 
south as Kentucky to end out the forecast period. Confidence remains 
low...however...for this late weekend/early work week system...as 
the GFS and European model (ecmwf) are still showing some disagreement on timing and 
placement. 


As for sensible conditions...the northwest flow and shortwaves will produce 
a series of frontal boundaries and Sparks for showers and 
thunderstorms. The first of these boundaries will have moved into 
the Ohio Valley region to start off the extended period...and will 
oscillate north and south but remain overall rather stationary 
through the first part of the weekend. Meanwhile...numerous 
localized surface low pressure systems will be driven by upper level 
shortwaves and generally push across southern Kentucky and Tennessee. This is 
where the bulk of the moisture and mesoscale convective system potential will lie. By 
Friday...the shortwave moving through will pass across the northern 
portion of the state...and the local surface boundary will align 
itself along the Ohio River. This time around...expect best moisture 
/rain and thunder potential/ to move across the entire 
state...continuing through much of the weekend but peaking during 
the afternoon and early evening hours. 


If the European model (ecmwf) model holds true...the strengthening upper level low 
moving southeast across Canada will bring a much stronger cold front across 
the northern Mississippi River valley Monday and into the Ohio River 
valley and points northward Monday night into Tuesday. Confidence on 
timing and the exact frontal location is still quite low 
however...given the discrepancies in the GFS and European model (ecmwf) this far out 
in the forecast /as mentioned above/. Stuck with a blend of these 
models...which led to just a mention of chance probability of precipitation during this time 
period. However...this system could bring another strong dose of 
strong showers and thunderstorms /pwats 2 inches an above/...and 
potentially some strong winds with 25 to 30 knots expected just 
above the surface and through the middle levels according to the latest 
gfs40. 


&& 


Aviation...(for the 06z tafs through 06z Tuesday night) 
issued at 150 am EDT Tuesday Jun 30 2015 


Convection has all but ended across southeastern Kentucky. 
However...model guidance suggests an isolated pop up rain shower will 
still be possible just about anywhere through dawn. Main challenge 
is fog. Most recent guidance suggest MVFR conditions or better at 
all of our terminals...only exception being sme LIFR conditions 
will be possible during the predawn hours. Guidance seems 
reasonable and therefore stayed close to guidance for general 
flight conditions. Scattered convection threatens once again 
Tuesday afternoon. Winds will remain light through early morning 
Tuesday before picking up out of the west...southwest at 5 to 10 
kts during the remainder of the day on Tuesday.
