Temperatures are the most noticeable weather feature this week as they have been well above normal since Monday and will remain that way until Sunday. There has been a good deal of sunshine each day and the region is still in a drought situation most locations east of the Foothills. The chance for rain is improving heading into the weekend, but not nearly as much as we need, and in some locations, not much at all.
The second feature that is important but not as noticeable is the dry pattern that has persisted for several months now. Although we are only officially down 3.73” for the year-to-date number, but we have a deficit of 2.21” since November 1st.
Needless to say, we are due for some soaking rains. Not going to happen with this event heading our way late Thursday and into Friday.
The rain arriving from the west Thursday night after sunset is associated with a cold front that will stall out and remain to our north and west through Friday. The origin of the next wave of air is from the south and southwest so that will be much milder and effectively shove the cold front to the north as a warm front. The next wave of rain will follow the warm air and arrive from the west on Saturday. The amount of rain expected is likely to be less than 0.25” generally, so not much relief for our parched earth.
The end result of the rain Saturday will be a much cooler air mass for the Commonwealth starting Sunday and lingering into the new work week. There will be some rain to our south Tuesday, but little will get above the 36 parallel.
Of Note: The Astronomical Winter begins on Tuesday morning at 10:58 as the direct rays of the sun are over the Tropic of Capricorn in the southern hemisphere, marking the start of the winter season. The Meteorological Winter began on December 1st.
The next few nights will be relatively quiet as far as the winds go, maybe a bit noticeable in the daytime, but overall “Frosty” should be fine to inflate heading into the weekend.
