Area forecast discussion, Jun 28, 11:05 PM PDT, 47 minutes before

Area Forecast Discussion
National Weather Service Spokane WA
1105 PM PDT SUN JUN 28 2015

.SYNOPSIS...
Triple digit temperatures are expected across parts of the Inland
Northwest again Monday. Scattered thunderstorms are expected over
the Cascades overnight, then spreading east Monday. Dry lightning
and the hot weather have the potential to raise wildfire concerns.
Tuesday and beyond will be mainly dry but continued very warm.

&&

.DISCUSSION...
A negatively tilted shortwave trough of lower pressure is
beginning to push into northern California late this evening.
Weak mid level instability will result in an increasing chance
for high based showers and thunderstorms through tonight. Best
chances are expected across the western half to two-thirds of the
forecast area. The primary hazard with these storms will be dry
lightning that results in new fire starts and strong outflow
winds. There have been reports of wind gusts of up to around 40
mph as this convection begins to move into WA. Strongest winds are
anticipated across the southern portion of the basin. Models are
showing this gust front weakening as it pushes further north, so
the northern portion of the basin may not see winds as strong;
however, this will likely be highly dependent on how much the
parent convection holds together. Blowing dust will also be a
concern across the basin with this gust front. Reduced visibility
will be a concern with the blowing dust, which will include the
I-90 corridor around Moses Lake to Spokane. /SVH

&&

.AVIATION...
06Z TAFS: A negatively tilted shortwave trough of lower pressure
will push into the region overnight through Monday. Showers and
thunderstorms developing out of northern Oregon will push up a
gust front through tonight. This gust front will likely be
strongest across the southern portion of the basin and gradually
weaken as it pushes further north. Timing of the gust front is
expected between 06-08Z for the KLWS, KPUW, KMWH and KEAT TAF
sites and between 08-10Z at KGEG, KSFF and KCOE TAF sites. Winds
may increase up to 30-40 kts with the gust front (especially at
KMWH) and shift from the south or southwest. A brief break in the
convection is expected overnight before more showers and
thunderstorms develop through the morning and afternoon on Monday.
Confidence is low at this time that the TAF sites will see
thunderstorms on Monday. /SVH
