For this morning's observed minimum temperatures - click Here Discussion: Tonight's forecast is the final forecast of the Fall Frost Forecasting Program. Orchard Rite will once again sponsor the Winter Arctic Outbreak Forecasting Program for south Central Washington - which will commence tomorrow, Saturday, and continue through the end of February. 6-10 day outlooks for possible outbreaks of arctic air into Central Washington will be issued Tuesdays and Fridays through the end of February, 2006. A weather disturbance moving southeast from the Gulf of Alaska will pass through Central Washington this evening. Showers and gusty southwest winds will accompany the disturbance, with clearing and decreasing winds in areas expected behind it overnight. Minimums should vary from the mid to upper 20s in the colder sheltered locations of the western part of the Yakima Valley to near 40 in the windier areas of the Basin. Protection might be needed in the western part of the Yakima Valley after about midnight with the inversion expected to become moderate with the loss of wind and clouds. Saturday and Saturday night is going to be interesting! A deepening low pressure system will move to the mouth of the Columbia River late tomorrow afternoon and through Central Washington early tomorrow night. Rain is expected to begin about midday and continue into the early hours of the night. As the low moves east, clearing will occur and minimums will once again drop to the mid to upper 20s in the sheltered locations of the Mid and Upper Yakima Valley to the lower 40s in the windier areas of the Lower Valley and Basin. The cold front associated with the low will hang up over northeastern Oregon Sunday and Sunday night, giving cloudy periods and a chance of rain to the southeastern part of the Basin. Minimums Sunday night should vary from the upper 20s in the western part of the Yakima Valley to near 40 in the southeast. The upper level trough following the low will move inland Monday with a westerly flow aloft setting up over our area Monday night into the latter part of next week. Bands of moisture embedded in the flow will give us cloudy periods with maybe a shower or two, but mainly over the mountains. Overnight lows from Monday night into the latter part of the week should hold in the 30s to lower 40s, though could dip to the mid 20s in the colder locations any night with prolonged clearing.
