Discussion
Very mild air for this time of year will stick around through Saturday, but then a strong cold front will arrive and bring an end to the current warm spell. Temperatures today and Saturday will continue at well above normal levels, but then we’ll turn noticeably colder late tomorrow night following the passage of the strong cold front. After a morning shower or two on Saturday, the approaching strong cold front will generate a narrow line of showers and embedded thunderstorms during the afternoon and early evening hours and some of the thunderstorms can be on the strong-to-severe side and contain brief downpours and gusty winds. Winds on Sunday will kick up out of the NW and temperatures will hold in the 40’s. Weak low pressure from the south-central US will head towards us on Monday and it could generate a couple of rain or snow showers. It'll turn warmer again by the middle of next week and more rainfall is likely on Tuesday and Wednesday, and then another cold shot should arrive for the second half of next week.
