Following the recent mild conditions, a significant pattern change will occur during the middle of this week. Tuesday will feature one more warm day of above normal temperatures, before a cold front drops temperatures to near normal on Wednesday. Conditions will continue to cool through the week, with below normal temperatures area wide by Friday and Saturday. High temperatures will fall from the 60s on Tuesday to the 40s and even 30s by Saturday. Low temperatures will drop into the 20s in many areas by Saturday morning. In fact, many areas will experience high temperatures later this week that are colder than the recent low temperatures. Locations like Pullman can expect high temperatures to drop 30 or more degrees between Tuesday and Saturday. Moisture appears to be limited, with no major storms expected to impact the region through Saturday. However, unsettled conditions will provide periodic chances for showers, which could be in the form of snow in some areas during the Thursday to Saturday time frame. Eastern areas like Pullman and Spokane have the greatest chance for light snowfall later this week, although most locations east of the Cascades have a chance of night-time snow showers. Accumulations generally appear unlikely at this point. While details for later this weekend and next week are uncertain, it appears that an unsettled pattern with mountain snowfall is possible. Temperatures after this Wednesday look to remain near to below normal for the foreseeable future, as more winter-like conditions return to Washington.
