Area Forecast Discussion National Weather Service Spokane WA 457 AM PDT Mon Jul 4 2022

SYNOPSIS. The 4th of July will see another round of showers and thunderstorms and will be on the cool side with highs in the upper 60s in the Panhandle to the mid 70s near the Cascades. The rest of next week looks to trend drier and warmer with showers and thunderstorms isolated and mostly over the mountains.

DISCUSSION.

Independence Day and night: The Inland Northwest will come under influence of an upper level pressure system for one more day. The low has meandered onshore with the center of the circulation situated over western Washington. A couple of shortwave disturbances will pivot around through this morning and afternoon. The first is moving into southeast Washington with showers and isolated thunderstorms forming out ahead across the southern to central Idaho Panhandle at 2:00 AM. This shortwave is relatively weaker than the next one that is quickly moving northward on its heels. This second shortwave disturbance will push up into the Inland Northwest later on this morning. Radar mosaic is picking up on showers associated with this next wave from northern California to central and eastern Oregon. Convective allowing models (CAMs) show a band of showers that will increase mostly over south- central to southeastern Washington after about 6 AM this morning. This band looks to pivot northeast through the morning into the Panhandle and then wrap northward across northern Washington by the early afternoon. Mid level instability will be a bit weaker with this feature with lightning expected to be fairly isolated with some embedded thunderstorms possible.

We then see surface based instability in the afternoon mostly across the Okanogan Highlands over the east slopes of the northern Cascades where sun breaks will be more likely earlier in the day. Dew point temperatures will be less this afternoon with P-wats also coming down from around an inch on Sunday to 0.6 to 0.8 inches today. This is due to some drier air that was entrained into the atmosphere over the region behind the shortwave that moved through on Sunday. The atmosphere will continue to be conditionally unstable, but this drier air entrainment will result in lower CAPE's today compared to yesterday. Surface based CAPEs off of the 00Z GFS and ECMWF solutions look reasonable with values in the range of 500-800 J/kg in that northwest corner of our forecast area. The lack of shear over that portion of our forecast area should limit how strong developing storm cells will get. We will still see the threat of heavy rain with thunderstorms, but much less of a severe threat due to wind/hail compared to storms that we saw in a higher CAPE environment on Sunday. With P-wats being lower compared to yesterday, it would seem that the threat for any flooding impacts will be any spots that received heavy rain yesterday and recent burn scars. Otherwise, there is less of a threat for flash flooding today. Will continue with the Flash Flood Watch as is, although, the Northern Panhandle has even less of a chances for seeing flooding impacts today compared to the rest of the areas under the watch.

Temperatures today will remain below average and cool for early July with highs in the mid 70s where we have more sun in central Washington and highs in the 60s over the Idaho Panhandle where we will see more cloud cover today.

Tuesday and Tuesday night: We start to dry out after an active 4th of July holiday weekend. Temperatures will rebound with back into the mid 70s to low 80s. Any threat of showers looks to be near the Cascade crest, over the Northeast Blue Mountains, and possibly right near the Canadian border over the far northern mountains. /SVH

Wednesday through Monday: The region will be a southerly flow pattern as it is in between a ridge to the East and a Low off the coast. It will lead to a warming trend for the region. Models have increased the amount the amount moisture with the pattern from previous runs. The Inland Northwest can expect periods of rain showers with isolated thunderstorms. The better chances are the ID Panhandle and Cascades. Afternoon winds will increase across the Basin. Gusts are expected to reach near mid 20 MPH. Highs for the period will be it the 80s and low 90s through the end of the week. Overnight lows will be in the 50s and low 60s. /JDC

AVIATION. 12Z TAFS: A deep upper level low pressure system will be situated over western Washington through this afternoon. There is ample boundary layer moisture across the northern mountain valleys where marginal VFR to IFR conditions around Republic to Colville and the Northern Panhandle. Showers will increase in coverage this morning as a shortwave disturbance rounds the upper level low. The atmosphere will destabilize with diurnal heating mostly over the Cascades to the Okanogan Highlands where the best chances for thunderstorms is expected for the afternoon. Thunderstorms over the east slopes of the Cascades will shift off the higher terrain toward KEAT, KEPH, and KMHW late in the afternoon into the early evening. /SVH
