Severe Weather Alert Descriptions

 Fire Weather Warning  Statement as of 4:14 am CDT on April 16, 2014


... Red flag warning in effect from 11 am this morning to 7 PM CDT
this evening for wind and low relative humidity for parts of Missouri...

The National Weather Service in St Louis has issued a red flag
warning for wind and low relative humidity... which is in effect
from 11 am this morning to 7 PM CDT this evening.

* Affected area... in Missouri... fire weather zones 019... 027...
035... 036... 049... 051... 052... 059... 060... 061... 062... 063...
064 and 065.

* 20ft winds... south 15 to 25 mph with gusts up to 35 mph.

* Relative humidity... as low as 22 percent.

* 10hr fuels... less than 9 percent.

* Impacts... these conditions are conducive for the rapid spread
and growth of uncontrolled wildfires.

Precautionary/preparedness actions...

A red flag warning means that critical fire weather conditions
are either occurring now... or will shortly. A combination of
strong winds... low relative humidity... and dry fuels can
contribute to extreme fire behavior.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service St Louis MO 
333 am CDT Wed Apr 16 2014 


Short term: (through late this afternoon) 
issued at 315 am CDT Wed Apr 16 2014 


Surface temperatures at 08z across the ongoing freeze warning 
remained in the mid to upper 30s. With increasing winds for the 
remainder of the night and only a few hours left until sunrise, it 
does not look like temperatures will remain at or below freezing for 
any appreciable length of time, therefore the freeze warning will be 
canceled with the morning package. 


Expect warm and dry weather today with highs in the upper 50s to mid 
60s, but the tightening pressure gradient ahead of a surface low 
over NE/South Dakota will lead to windy conditions, especially during the 
afternoon. At this time, the forecast winds do not meet lsx criteria 
for a Wind Advisory (sustained winds of 30-39 mph/26-34 kt and/or 
gusts of 45-57 mph/39-49 kts), therefore no wind headlines are 
planned. If the actual winds today end up being stronger than 
currently forecast, then a Wind Advisory may eventually be needed, 
especially for parts of central/northern MO where the gradient will 
be tightest. 


The combination of strong and gusty winds, low rh, and low fuel 
moisture values will produce red flag warning conditions across 
parts of the area. Please see the fire weather section below for 
additional details. 


Kanofsky 


Long term: (tonight through tuesday) 
issued at 315 am CDT Wed Apr 16 2014 


Surface low and upper vort Max move through Iowa into WI tonight, 
leaving a trailing cold front stretching from WI into northern MO 
and central Kansas. The wind shift and temperature contrast across the 
boundary are not terribly impressive tomorrow, but with a vort Max 
forecast to approach and move across the area, the boundary could 
provide a focus for rain showers during the afternoon and evening. 
Instability parameters look weak therefore kept thunder out of the 
forecast. 


It's not clear whether the aforementioned boundary washes out in 
place or sinks a bit farther south tomorrow night, but a new warm 
front should develop somewhere in the region on Fri/Sat as another 
surface low develops to the west in response to an approaching 
upper vort Max. European model (ecmwf)/Gem/GFS all show different orientations for 
the warm front which extends from a surface low over South Dakota/ND, co, or 
both depending on which model and which run. Over the last couple 
of days, the model solutions for Fri-Mon have varied quite a bit 
compared to their previous runs (particularly with regards to the 
location of surface synoptic systems and the placement of upper 
vorts), and tonight's runs are no exception. Since the models seem 
fairly insistent that some kind of low pressure system ought to 
affect this part of the country late in the weekend or early next 
week, chance pops for sun/Mon look like an acceptable compromise 
in light of the model uncertainty.

Fire weather: 
issued at 315 am CDT Wed Apr 16 2014 


Red flag warning conditions are expected for parts of central, 
eastern, and northeastern MO today with a heightened fire danger 
elsewhere. The wfas forecast of 10hr fuel moisture for this area 
is 7-8% for today. Southerly winds will increase during the 
morning hours and remain gusty through the afternoon. Expect 
sustained winds of around 20 mph gusting to around 30 mph, 
possibly higher at times. Minimum afternoon relative humidity 
values should fall to 20-30% with the lowest values across parts 
of central and northern MO. Since rfw criteria for wind and fuel 
moisture will be met nearly everywhere this afternoon, the area 
covered by the rfw is based on a forecast of where minimum relative humidity 
values are expected to fall below 25%. Depending on dew point and 
temperature trends, the rfw might need to be expanded today.
