Current Weather Conditions for Tuesday March 27, 2012

Current Conditions
Temperature (Fahrenheit) - 68 degrees F
Wind direction - WSW
Wind speed - Gusting between 15mph and 30mph
Barometric pressure - 1029.51 g/kg
Cloud Cover - Broken (Cumulus Mediocris)



Despite a rather brisk morning, temperatures were still much warmer today than averages this time in March. My prediction was correct in that regard and we saw a little drizzle here and there but no spring showers. However we may be in store for some spring thunderstorms tonight. Possible thunderstorms are indicated by cumulus cloud formations and that have grown vertically throughout the day along with the wind direction shifting to more of a SW direction. In order for thunderstorms to come to fruition a SW wind needs to continue along with a more vertical growth in the current cumulus clouds.



Looking at the water vapor satellite image it doesn't appear as though there is an abundance of water vapor in the area currently.

However with an LI rating of 10.6 and a KI index value of 31 we have rather contradictory information on the possibility of a thunderstorm. The LI index indicates the atmosphere is very stable, yet the KI index indicates an 85 percent chance of thunderstorms. In my personal opinion I see a low chance for thunderstorms tonight and cooler temperatures than today for tomorrow. That said I will be keeping my eye on the clouds, looking for vertical growth.
