NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Boise Idaho 
322 am MDT Tuesday Jul 22 2014 


Short term...today through Wednesday...we remain in SW flow aloft 
with a moist atmosphere and above-average shear and instability. 
This combination led to a great deal of lightning yesterday... 
especially in southeast Oregon. Chances are good that we will have a 
significant convective event again today. We have increased probability of precipitation 
and thunderstorm coverage over most of the area...especially for 
late this afternoon and tonight. Storm Prediction Center has US in a /see text/ 
area...meaning we are near their threshold for severe weather. A 
vorticity maximum located near 33 north 127 west as of 2 am MDT was moving NE. 
This will accelerate later today as it heads toward the area. Lift 
associated with this vorticity maximum will aid thunderstorm development 
late this afternoon and this evening. This vorticity maximum is associated 
with a jet maximum of around 90 kts at 300 mb. This will provide ample 
shear to maintain long-lived and organized thunderstorms. Precipitable water 
values are between 0.75 and 1.00 inch across the area...so storms 
will produce heavy rain in the cores...along with hail and gusty 
winds. Storm motion will be northeast around 40 miles per hour...increasing 
the chance for strong winds but decreasing the chances for flash 
flooding. The convection will continue well into the night... 
although it will decrease in areal coverage and intensity after 
midnight. A red flag warning has been issued for most of the fire 
weather zones because of the anticipated lightning. See below for 
details. Wednesday...as a strong trough moves by to our north...we will 
find ourselves in a dry slot and most of the convection will be to 
our north and west. However...we still have slight chance to 
chance probability of precipitation and a slight chance of thunderstorms in the northern 
quarter of the County Warning Area. Temperatures will be near normal today and Wednesday. 


Long term...Wednesday night through Monday...an upper level trough 
will move northeast across Washington Wednesday night...then along 
the Canadian border and east of The Rockies by Thursday night. 
Following this system westerly flow aloft will bring much cooler... 
drier...and more stable air across our area. High temperatures on 
Thursday will be around 10 degrees below normal with mostly sunny 
skies. A warming trend will commence on Friday and temperatures will 
return to near normal on Saturday then above normal on Sunday and 
Monday as The Four Corners upper level high rebuilds over the 
northern intermountain region. High temperatures on Monday are 
expected to be near 100 degrees in the lower valleys. 


&& 


Aviation...VFR except local MVFR conditions with thunderstorms. 
Isolated showers and thunderstorms this morning will become 
scattered to numerous by 00z and continue through tonight...mainly 
north of a kbno-kmuo-ksun line after 06z. On Wednesday expect 
isolated to scattered showers and thunderstorms mainly over the 
mountains of Baker County Oregon and central Idaho. Surface 
winds...variable around 10 kts except gusts to 40 kts near 
thunderstorms. Winds aloft...southwest up to 20 kts at 10k feet mean sea level.
