Area Forecast Discussion
National Weather Service Spokane WA
743 PM PDT Fri Apr 12 2024
.SYNOPSIS...
The upcoming weather into the weekend will feature a few chances
of mostly mountain showers and thunderstorms with a warming
trend. High temperatures for much of the area will climb into the
70s over the weekend. A cold front will bring a return of cooler
and showery weather early next week. Cold front passage will bring
windy conditions Sunday night through Monday.

.DISCUSSION...
The forecast for the rest of the night has updated to refine the
area of rain showers across southeast Washington into the central
and southern Idaho Panhandle. As of 730 PM, it looks like the
northern extent of decaying convective showers will move across
Whitman, Asotin, Lewis, Nez Perce, Latah, Benewah, and southern
Shoshone counties this evening. Some lightning and thunder will be
embedded within these showers mainly to the south of Lewiston and
Dworshak Reservoir. Radar reflectivity values have decreased
significantly since thunderstorms formed late in the afternoon
southwest of Baker City. Given recent radar trends, it looks like
the threat of any hail has passed.
For the remainder of the Inland Northwest including central and
northeast Washington and far north Idaho, clearing is expected
through the night as upper level high pressure strengthens.
Overnight lows will be in the 40s. Patchy valley fog will be
possible in the sheltered valleys of the central and southern
Idaho Panhandle where rain falls this evening. Spots like Bovill,
Clarkia, Calder, and Avery may experience some reduced visibility
prior to and shortly after sunrise. /GKoch
