Cold and plenty of it continues to flow into the United States today with a flow of air from the north. Another blast of arctic air is entering the country across the Rockies and this air will flow east and be with us much of this week.

Today is a milder day than yesterday when most areas where in the 30s all day long. These kinds of temperatures are more conducive to the middle of December, not November. Highs this afternoon reach the upper 30s to lower 40s today, so we will be adding about 5 degrees to yesterday’s readings.
Clouds will be increasing throughout the day, but there won’t be any precipitation. Overnight the clouds thicken. Temperatures remain in the upper 20s and lower 30s with the clouds and a southerly flow of milder air.

Tomorrow a low pressure area will pass over the region bringing rain to most areas with some snow across the northern ski mountains.
I am expecting half and inch to perhaps an inch of rain over extreme south coastal areas. The precipitation will begin as snow in many areas, but quickly change to rain. There could be some slippery spots Monday morning, but along the coast enough warm air will move in from the ocean to change the wintry precipitation to rain. In the mountains look for 2-5 inches of snow before it mixes with some sleet and freezing rain and then ends. I focused the map on the mountains as this is where the most snow will occur.

The chart below shows how much rain is expected and what our temperature range will be the next 7 days. Notice how close to freezing we remain, again more like December or even January.

As the storm moves into Canada a blast of cold air will follow and temperatures will be below average the rest of the week. Highs on Wednesday will stay in the 30s and will continue in the 30s to lower 40s the rest of the week and into the weekend.

Next weekend some of you will start the exodus to family and friends for Thanksgiving. Many colleges are off so students will be heading home for a vacation. The weather looks dry and cold next weekend.

All models are agreeing there is going to be sizeable coastal storm early Thanksgiving week. The track of the storm will be critical as to whether it’s a rain or snow situation or it goes out to sea. It might be 555 and raining or 30 and snowing, so it’s pointless to speculate. Since the models agree a storm will form, the question I’ll be trying to answer this week is where, when, and how much of anything will fall.

The details are important of course, but at least we know the atmosphere is going to be very active around the 24th of the month.
Presently, Thanksgiving Day looks cold and dry with highs significantly below average.
