The vigorous upper level weather system that brought active and windy conditions to the area yesterday has now passed off to the east into Montana. A northwesterly flow aloft is setting in as an upper level ridge of high pressure begins to build into the area. Winds will remain breezy through the morning but the gradient will weaken appreciably during the day with decreasing winds by afternoon. Northcentral Washington can expect sunny skies today, a northwest wind 10-15 mph and afternoon high temperatures today into the mid and upper 40’s.
Tonight and Tuesday will be a quiet weather period as an upper ridge builds and crests over the area. Mostly sunny in the Wenatchee Valley for Tuesday as well with highs again in the mid to upper 40’s.
A few more clouds expected on Wednesday and warmer with afternoon highs in the lower 50’s.
Thursday through Sunday weather models are in remarkably good agreement in building another broad ridge of high pressure over the northwestern U.S. and directing the moisture feed to the north into Canada This will result in dry conditions across the Inland Northwest for Thursday and Friday as the ridge axis approaches and passes through . It will also promote a noticeable warming trend especially on Thursday and Friday as the air flow becomes southwesterly. Friday looks like the warmest day of the week with basin locations lofting into the mid50s for high temperatures with upper 40s to lower 50s even in the northern valleys.
Saturday will remain mild with highs in the lower to mid-50’s but with an increasing chance of mainly late-night rain showers with snow confined to the higher mountains. Back to mostly sunny skies for Sunday with afternoon high temperatures in the lower 50’s.
