KEY MESSAGES

- Below normal temperatures with breezy conditions through Wednesday.

- Warmer temperatures and dry weather Thursday through the holiday weekend.

DISCUSSION

The upper level trough that has been over the Western CONUS will gradually weaken and the flow will become more zonal by Friday and more southwesterly by the weekend. Will need to keep an eye on the southwesterly flow or any shortwaves but right now it appears to be a dry holiday weekend.

In the near term, some shortwave energy today will bring rain chances mainly to Wallowa County and low (<20 percent) chance of thunderstorms.

Winds will continue to be gusty today and Wednesday, especially in the Kittitas Valley, Simcoe Highlands and potions of the Columbia Gorge and north-central Oregon. Winds could gust in the 25 to 35 mph range with locally higher values.

The trough will begin to flatten and heights will rise and temperatures will begin to rise towards normal by Thursday and then into the lower 90s in the Columbia Basin over the weekend. These values would be about 5 or so degrees above normal. As temperatures warm, RH values will decrease to the 10 to 15 percent range in many areas over the weekend, but winds should be relatively light by this point.

There is considerable disagreement as we get toward the end of the period and beyond as to the extend of the ridge building in. Some guidance suggests we will have the typical summer ridge and a return to heat, while other guidance is not so bullish on that. We will have to see how this plays out in the early to mid July timeframe.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

VFR conditions are expected through the TAF period. Winds will gust 20 to 25 kts at most sites before decreasing this afternoon/evening and 25 to 30 kts at DLS.
