CHILLIER AIR ARRIVES FOR THE WEEKEND
Overnight, skies will be clear, winds will die down and temperatures will fall quickly to the upper 30s to low 40s. You will notice the chill more so than recent mornings.

DMA Forecasted Lows With Madis

Highs will be mild once again in the mid 50s. Winds increase through the day as the front sags south. They shift from the west to the northwest 10 to 20 MPH  with gusts to 30 MPH. Low temperatures leading into the weekend drop to the upper 20s and low 30s, a much colder start then recent mornings. The day starts with sunshine, but clouds moving in by afternoon, quickly dim the bright skies. High temperatures in the mid 40s, fall short of seasonable averages.

GROWING RISK FOR SPRING SNOW
As the next system rides up the coastline, precipitation arrives as early as overnight Saturday. It will fall in the form of snow and may lightly accumulate by morning. With the higher March sun angle and daytime temperatures in the 30s to near 40, rain may mix in with the snow. As the sun sets, the rain/snow mix transitions back to snow. There is considerable differences on the models of the exact solution, however, confidence is growing we could see accumulating snow.

Any accumulations would be on grassy surfaces since roadway temperatures this time of the year are much warmer and not supportive of accumulating snowfall. It is not out of the realm of possibility for snow this time of the year. Here is a look at the biggest snow storms after March 17th. Below average temperatures in the 40s, continue into the beginning of the week.

MID TO LATE WEEK OUTLOOK
Trough exits the area allowing for a ridge of high pressure to build in mid-week. A stray shower is possible Wednesday, otherwise it will be dry with partly cloudy skies with milder temperatures near 60 degrees. It warms even more, into the upper 60s, under brighter skies Thursday.
