Area forecast discussion...updated 
National Weather Service Jackson Kentucky 
1055 PM EDT Tuesday Mar 31 2015 


Update... 
issued at 1055 PM EDT Tuesday Mar 31 2015 


The winds are starting to settle more effectively late this 
evening along with higher relative humidity levels. Accordingly have updated the 
severe weather potential statement to remove the fire weather cautions for the evening period. 
Have also touched up the grids via the infusion on the latest 
shortblend guidance...obs...and trends. These updates have been 
sent to the ndfd and web servers. 


Update issued at 810 PM EDT Tuesday Mar 31 2015 


23z surface analysis shows a dry cold front dropping through eastern 
Kentucky. This is supporting breezy and dry conditions through the 
area this evening. This has led to several wild fires developing 
through the area earlier in the day that continue...as seen on the 
dual pol radar loops...cirrocumulus in particular. The winds will slowly 
settle through the rest of the evening as the pressure gradient 
relaxes and the mixing heights fall. Accordingly...have allowed 
the red flag warning and Special Weather Statement for fire weather concerns expire. 
However...did continue the cautious wording in the severe weather potential statement for the 
rest of the evening for near critical conditions. Also fine tuned 
the T/dew point grids per the latest shortblend guidance...obs...and 
trends. Finally...took sky cover down another notch with this 
update. These grids have been sent to the ndfd and web servers 
while an updated zone forecast product and severe weather potential statement were issued. 


&& 


Short term...(this evening through Wednesday night) 
issued at 345 EDT Tuesday Mar 31 2015 


Current conditions across the area feature mainly clear skies 
with a an upstream dry cold front moving southeast. As of 
19z...the front is moving across the Ohio River and into eastern 
Kentucky. With this...a strong gradient will be present with some 
20 to 25 knot gusts and this will continue with and behind the 
front. Expecting winds to decrease and decouple by 23z this 
evening. Profiles this evening continue with a deep dry layer and 
will keep skies mostly clear through tonight as well. While the 
center of high pressure will not have moved into the area...some 
Ridge Valley split will still develop tonight. The dry air this 
evening and gusty winds with the cold front will allow for some 
hazardous fire weather conditions and will keep this in the severe weather potential statement. 


Heading into the day on Wednesday...middle level ridging will be 
moving into the area with surface high pressure centered over the 
Ohio Valley. Winds will be light during this time and with the 
higher sun angle...temperatures will rebound into the middle 60s 
despite the cold front passing through on Tuesday evening. Still a 
dry air mass will be in place with afternoon relative humidities 
dropping into the lower 30 percent range. 


For Wednesday night... a strong short wave moves into the MS River 
Valley as southerly flow increases into the Tennessee and Ohio Valley. A 
weak disturbance moves northeast out of the Gulf and into Kentucky 
bringing a chance for showers into eastern Kentucky by dawn on 
Thursday. By dawn on Thursday...a strong cold front develops as 
this waves moves into the Midwest. Forcing and instability looks 
to be strong enough that a few thunderstorms may move into the 
area by dawn on Thursday. For now will stay with chance showers as 
there will be some dry air to overcome as well. 


Long term...(thursday through tuesday) 
issued at 357 PM EDT Tuesday Mar 31 2015 


The Ohio River valley will find itself in transition during the day 
Thursday...as upper level ridging begins to exit...and a subtle 
longwave trough over the western half of the Continental U.S. Begins to shift 
eastward. Expect this longwave trough to make it into the 
Mississippi River valley...and then then Ohio River valley by Friday 
evening. Meanwhile...a strong shortwave will traverse southern 
Canada just ahead of this longwave trough. Models are in 
surprisingly good agreement with these features...other than a few 
slight timing differences...and continue to be so throughout the 
weekend as the trough axis exits. Zonal flow and general ridging 
will then take hold Sunday night through the remainder of the 
forecast period. 


Two surface low pressure systems will set up along the longwave 
trough and shortwave as we head into the extended. By 12z 
Thursday...expect these surface low pressure systems to be 
located...one...just north of Lake Superior...and 2...along the 
Southern Plains. An extensive cold front will link these two 
systems...quickly sweeping eastward with the longwave trough 
movement. 


With southerly flow already in place...and a good pull of warm moist 
air coming off the Gulf of Mexico...expect convection to begin 
developing during the day across Kentucky...well ahead of the cold front. 
Coverage and instability will increase as the cold front nears 
Thursday night. By Friday morning...the southern-most low pressure 
system will be in mi/AR...and the northern one will have raced 
farther ahead and northward into far NE Canada. The cold front will 
be located along the Ohio River and become nearly stationary as it 
becomes further elongated from west to east. This large area of 
frontogenesis/instability will increase convective activity Thursday 
night and into Friday...with 6 hour precipitable water values well over 1 inch 
Thursday afternoon through Friday morning...increasing to over 1.25 
inches during the day Friday. As such...expect flash flooding to be 
a concern as we head into the day Friday...especially under some of 
the larger showers and thunderstorms. 


Friday evening...the front will finally make a very quick shift 
across Kentucky Friday evening...pulling in much drier and somewhat cooler 
northwest flow. This will also kick in a subsidence inversion...preventing 
any further thunderstorm development...and quickly cutting off best 
quantitative precipitation forecast. Expect showers and any lingering thunder to taper off 
overnight. European model (ecmwf) tries to hold onto some upslope flow through the 
first half of the day Saturday...while the GFS pulls the front far 
enough southeast that there is no lingering moisture influence. Expect it 
will likely be a combination of these two solutions...so will keep 
with a model blend of precipitation through the day Saturday. Any 
additional accumulations will be very light with very little 
moisture left in the soundings. 


More zonal upper level flow will take hold through the remainder of 
the weekend. After a drop in temperatures from the cold frontal passage on 
Saturday...expect them to slowly moderate to near or above normal. 
However...both the European model (ecmwf) and GFS are trying to develop a weak 
frontal boundary along this zonal flow as we head from Monday into 
Tuesday...with strong southerly flow and abundant moisture flowing 
into the Ohio River valley off of the Gulf of Mexico. If this 
continues to organize...could be looking at another chance for rain 
and thunderstorms...though there is still quite a bit of 
disagreement on intensity and coverage. 


&& 


Aviation...(for the 00z tafs through 00z Wednesday evening) 
issued at 825 PM EDT Tuesday Mar 31 2015 


VFR conditions will continue through the period. A cold front is 
moving through the area this evening with west to northwest winds 
gusting to between 20-25 kts. These winds will subside over the 
next couple of hours with no AVN concerns through the remainder 
of the period as skies remain mainly clear and the winds stay 
light into the day Wednesday.
