April 10, 2018

Temperature: 32°F
Dew Point: 22°F
Wind: W 5 mph
Precipitation: 60%

Nothing was predicted in the forecast for the day. And if you look at any general weather station, it is a shock as well that April Snow Showers are falling on this Tuesday morning. Typically, when a high pressure system moves in, it doesn't spring precipitation (at least in what I've noticed after writing past blogs). However, in front of the stationary front there is a little cloud that has recorded some sort of preciptiation in the Twin Cities/Eau Claire area.

Most of the moisture remains over the northwest coast by Washington and Oregon. The Midwest is by no means dry, so this could be a reason for the few flurries that we are having.

Unpredictable weather senarios could arise with the breaks in the jet stream, especially in the trough of the Midwest or the upward push over the Rockies.

Based on the high pressure system and the shifting jet stream, I forecast that temperatures will continue to rise as the week comes to a close. And if anymore precipitation in the air falls, it will be rain and not snow since temperatures will be above 32°.
