Next Storm/Next Snow Forecast Discussion from the Cherrywood Observatory – March 18, 2019

Forecast Discussion:

Wonderful quietness keeps being quiet. The snow is vanishing quickly in most locations across the lower elevations. Figure 1 shows our weak front has pushed down across the state, so we'll only be in the upper 40's F today. But it still will feel nice. The atmospheric moisture (water vapor) satellite image- Figure 2 - shows just dry air upstream of our state.

The longer range forecast:

We return to normal temperatures Wednesday and climb to above normal by the weekend. Another (fairly weak) cut off low forms in the southwest U.S. and pumps some moisture up later in the week, but we'll be above freezing day and night - expect some rain chances for a change. Nothing scary. (I call rain self-shoveling-snow.)

Enjoy it! (I'm perched on a narrow data stream in the central AZ mountains this week for Spring Break. I won't say what the weather is like out here.)
