Warm for a few more days, then get ready for an arctic blast
Warmer that average temperatures should stick around for the weekend and even early next week. But, as we have discussed in previous posts, get ready for an arctic outbreak by midweek.
MILD 1ST WEEKEND OF DECEMBER
Patchy dense fog and clouds Saturday Morning with temperatures in the 40s. A few sprinkles or patchy light rain east. Clouds could gradually break away during the afternoon. Temperatures should eventually reach the upper 50s on the mountain tops to the low/mid 60s by late afternoon at valley locations. A little colder Saturday Night under a clear sky and temperatures dipping to between the 30s to bear 40. Then, with more sun on Sunday, afternoon temperatures should return to the low/mid 60s.
Monday also looks warmer than average with a mix of sun and clouds and afternoon highs back into the 60s.
BRACE YOURSELVES.....WINTER IS COMING!
A strong cold front arrives on our doorstep late Tuesday bringing in a more widespread chance for rain and even some thunderstorms. Right now, the risk of severe storms looks low. But, as always, we will keep you updated. Soaking rainfall from Tuesday Afternoon through Wednesday Morning could produce rainfall amounts around 1.25". Temperatures should remain warm on Tuesday with low 60s, but then the bottom falls out by Wednesday!
Much colder air should quickly move in early Wednesday. The European Model shows the chance that the rain could move out slower Wednesday allowing for the colder air to produce a period of "wintry mixing", Now, typically, systems like this have the moisture outrunning the cold air. We'll just have to watch this in the days ahead. If we do get some "mixing" Wednesday Morning, it looks short in duration. But, again, we'll watch it.
Either way, the bigger story is the arrival of the first arctic blast of the season. Temperatures Wednesday Afternoon should stay in the upper 30s to lower 40s along with a brisk northerly wind making it feel even colder. The strong north-northwesterly upper flow could even bring in a few upper level disturbances Thursday and Friday. This means the chill will continue. And, some cloud cover and even some flurries or patchy light snow. Right now any amounts look very light and not problematic. High temperatures Thursday and Friday only in the lower 40s and morning lows in the 20s.
The following weekend of Dec 9-10 remains very cold with highs potentially in the 40s and morning lows in the 20s.
As always, you can depend on the StormTrack 9 Team for updates!
