NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
449 PM PDT Thursday Apr 24 2014 


Synopsis... 
a cool and showery weather pattern will linger through the 
weekend. A significant warming and drying trend is expected 
Monday through Thursday of next week as high pressure builds over 
the area. 


&& 


Discussion... 
tonight...a large upper level trough along 130w will result in a 
southwest flow over the inland northwest tonight. An upper level 
wave associated with this trough will track into northeast 
Washington and Idaho Panhandle through early this evening which 
combined with surface instability will trigger additional 
showers. Models also continue to show a favorable environment for 
isolated thunderstorms with uncapped cape values of 400-900 j/kg 
which combined with 0-6km shear values of 20-25 kts could lead to 
a few stronger storms capable of producing hail and gusty outflow 
winds. This shear is a bit stronger up to 40-45 kts from the Blue 
Mountains to the central Panhandle mountains where the best 
potential for strong storms lie. Convection will die down after 
sunset as the loss of daytime heating stabilizes the lower 
atmosphere. Overnight another mid level disturbance will track 
into California and Oregon with a few showers possibly creeping up 
as far north as Lookout Pass and the Palouse. A few showers will 
also be possible near the Cascades due to upper level diffluent 
flow and a weak wave tracking across the area. Otherwise the 
majority of the central and eastern Washington into the north 
Idaho Panhandle should stay dry overnight. Jw 


Friday through Sunday...a somewhat active weather pattern 
will continue Friday through the weekend. Friday the main upper 
level low will move across the region and slowly fill Friday and 
early Saturday. Saturday night the next upstream negatively low 
will begin to nose into the region from the west. 


Friday...the models are in good agreement of the upper level 
cold core tracking through the Pacific northwest. The leading 
edge of the trough moving through my south/southeast zones will 
result in enough forcing...combined with lingering low level 
moisture for a chance of precipitation across my south/southeast 
zones early in the morning...otherwise just a few showers possible 
in westerly flow. By afternoon the 500 mb temps drop to around -28c, 
with lapse rates increasing to 7c to 8c/km as the cold core moves 
through. The models are picking up on a few sheared out little 
waves through the day but no significant forcing mechanism. In 
addition we lose the deep moisture tap that was over the region on 
Thursday. Convective showers could develop just about anywhere in 
this regime through the afternoon hours...but the focus will be 
across the northern mountains and across the southeast zones. 


Friday night into early Saturday the upper level low begins to 
fill and shear apart as a strong jet moving into SW or and 
norcal tears the trough apart. This should bring a dry period to 
much of the forecast area through Saturday morning. The exception 
will be across the southeast zones north through the central 
Panhandle where ample low level moisture and south-southwest up- 
sloping flow will keep a good chance chance of rain and mountain 
snow in the forecast. The remains of the sheared out low finally 
lift northeast through the Panhandle Saturday afternoon for 
continued moderate shower potential mainly for the Panhandle but 
now looks like it may Bend back towards the northeast mountains as 
well. 


Another negatively tilted trough will nose into the coast Saturday 
evening...then lifts northeast through the Panhandle on Sunday. 
The models have slowed the timing of the warm front down a bit 
from previous runs. Moisture and isentropic up-Glide will increase 
after 06z along the Cascades and move through the forecast area 
through the early morning hours. The following weak cold front 
follows about 6 hours later and weakens further over north Idaho 
by Sunday afternoon. This will result in another round of light to 
moderate stratiform precipitation moving through the forecast area 
Sunday morning. Precipitation then turns to showers Sunday 
afternoon mainly across the eastern half of eastern Washington and the 
Idaho Panhandle. /Tobin 


Sunday night through Thursday...cluttered dirty low amplitude 
ridge with plenty of moisture and impulses streaming through it 
keep Sunday night through Monday night somewhat potentially 
unsettled with pops of various shape or form for convection and 
generally light precip amounts. The general cloudiness and pops 
allow for forecast daytime highs on the cool side of normal with 
overnight lows on the warm side. The ridge is expected to amplify 
substantially resulting in a significant warming and drying trend 
Tuesday through Thursday with models varying somewhat in the 
placement of the ridge axis. For now given the model solutions it 
seems reasonable to continue with the warming and drying trend and 
having it peak on Thursday and start to look for signs of a day to 
pick out where this ridge is then broken down to add either pops, 
wind, and cooling. /Pelatti

Aviation... 
00z tafs: showers and embedded thunderstorms will continue to 
develop through 02-03z across mainly the eastern third of the 
forecast area...before convection falls apart. The showers may 
contain brief heavy rain...small hail and gusty outflow 
winds to 40 mph. Conditions will be mainly VFR except for a brief 
period if a shower develops in the vcnty of a taf site. After 
sunset conditions will settle down through the night. However 
moisture moving up from the south will move north along the Idaho 
Panhandle and result in cigs dropping to around bkn-ovc100 after 
10-12z. Klws will see cigs drop below ovc100 but remain VFR with 
an increasing chance of -shra after 07-08z...then lingering 
through the day. The precipitation should stay south of kpuw...but 
did add vcsh through the afternoon for the remainder of the 
eastern taf sites. /Tobin
