Monday's Weather

Today’s Conditions

Temperature: 24F
Wind: 14 mph NW gusts 30 mph
Dew Point: 12F
Humidity 62%
Pressure: 30.32" rising

The small area of low pressure that has been sitting over Wisconsin moved out last night and is now over the eastern great lakes area.  The pressure continues to rise and give way to a high pressure system coming out of the North West.  The skies are beginning to clear there's cumulous nimbus clouds replacing the stratus clouds that contributed to the gloom of yesterday.  The satellite shows nice clear skies on the way for the rest of the day. 


However there is a huge low pressure system building in the Rocky’s at the moment and will quickly push out the high pressure. This low pressure may turn out to be an exceptionally powerful storm and will be watched closely for the next few days.


The surface data shows what is now a stationary front in the northern Rockys that front is expected to gain strength and move towards us. The data also shows the North West wind pushing out the clouds and keeping the temps relatively cool today. 


This forecast model shows the predicted amount of precipitation that can be expected in the next 48 hours.  As you can see we are right in the path a significant storm. 


This map shows the forecasted pressure systems for the next 48 hours. It's projecting a very intense low pressure system to break away from the Rocky’s and gain strength as it moves toward Minnesota.  This low pressure is defiantly going to produce precipitation.  It’s course and development will determine just how hard we get hit in Eau Claire.  The surface data is showing the driving mechanism behind this storm. If you look at the wind coming out of the gulf it's heading north east, then  getting pulled west over the great lakes and in to Canada, then its swirling back though Wisconsin.  This air contains a lot of moisture that will provide energy to coming storm.  The current relative humidity map also show this.  There is very moist air to our north east and west that’s starting to get pulled down towards us.  The amount of moisture and the speed at with this happens will have a serious effect on how the storm will develop. We'll have to keep a close eye on all of these factors as this is expected to be the most intense storm of the winter.
