Rain to Snow

today

Weather Headlines

–Rain changing to snow today

–Snowfall accumulation of up to one inch is possible by midnight

Main threats

Be careful on area roadways from this afternoon through Wednesday morning. Snow and ice will likely lead to some slick spots.

Temps will be turning sharply colder tonight. Make sure the people in your life are ready for the cold. Also, make sure your pipes and outdoor pets are ready for these freezing cold temperatures.

Summary

We’ll see rain transition to snow as we go through the day. The precip should be all snow by the afternoon hours across the whole plateau.  A second surge of moisture for this evening is depicted in most of the models. That will be when the best opportunity for some accumulating snowfall will be. Accumulations of up to one inch are possible for all of us by midnight. Be careful on area roadways.

The other big story will be the much colder temps that will be settling in. Make sure people, pipes, and pets are taken care of. Remember, those outdoor fur babies have gotten used to the milder air. This cold snap will be hard on them without adequate, dry shelter.

Tomorrow is still looking pretty good. We will see more sunshine but it will sure be cold. Make sure you bundle up.

On Thursday, clouds will be increasing ahead of our next storm system. It now appears temps will warm up just enough for this system to be all liquid. The only exception might be at the very onset, when precip may mix for a short period of time. I’ll continue to monitor this.

That system will produce showers for us on Friday. Right now, it looks like most of Saturday will be dry, although it will likely remain cloudy. I may have to add some Saturday morning showers back into the forecast but I left it dry for now.

Yet another big rain-maker arrives Monday.

Tuesday Clues Day

Have you ever noticed a ring around the sun or moon? Those rings indicate that moisture is increasing in the upper-levels of the atmosphere. This can precede an incoming storm system by about 24 hours or so. These rings are seen in all seasons of  the year. It’s not a 100% guarantee that wet or snowy weather is coming, but it’s accurate most of  the time.

It’s interesting to note that the ice crystals that help create this ring always the refract the light at a 22-degree angle. That means the ring will always be 22 degrees out from the sun or moon.

So, the next time you see one of those rings, you better make sure you’re ready for rain or snow!
