Current weather Conditions for Saturday April 21st, 2012

Current Conditions
Temperature - 50.8 degrees Fahrenheit
Dew point - 29 degrees Fahrenheit
Relative humidity - 43%
Wind speed - 3 mph, gusting up to 6 mph.
Wind direction - E
Barometric pressure - 1029.87 g/kg
Cloud cover - overcast (stratus)



As I had predicted in yesterday's post, cloud cover has returned this evening after nice clear conditions throughout the morning. Take a look at where the mid-latitude cyclone, which I referenced in yesterday's post, is currently.



Looking at the water vapor satellite image you can just barely see the mid-latitude cylclone. However is the series of low pressure systems that came through Wisconsin and many other states, just a few day ago, is quite evident over the Eastern sea-board.



Although this mid-latitude cyclone is not very strong we will still some rainshowers, very soon I expect. Currently temperatures are similar in the airmasses west and east of the mid-latitude cyclone, however the airmass to the west has a higher moisture content. As we have covered previously, this is known as a dryline and is the reason for the precipitation that will occur within the next hour. As for tomorrow morning the Eau Claire area could still be experiencing rainshowers. From late afternoon on cloud cover will begin to clear however.
