The Storm Report Blog For February 25-26, 2013
Left Map Analysis: The latest satellite image shows the sub-tropical jetstream flowing over Mexico into the western Gulf of Mexico and on towards the Gulf Coast. This jet is going to interact with a very powerful Polar front jet that is moving out of Colorado into Texas. This is going to set the stage for a significant winter storm and also a moderate outbreak of severe weather for the next 24-36hrs across a good portion of the country.
Right Map Analysis: The current position of the surface low pressure is over the four corners region, this will push out into the Texas Panhandle before taking a turn to the northeast. The yellow dash lined is our forecasted track for the next 24hrs of the low pressure center into the first part of the 26th. This storm is going to be very robust with a winter side and severe weather side to it. Looking at the green line is the outlined area for the moderate rain that will move just south of the low’s track. The pink line represents where the mix of rain and snow along with some freezing rain will occur over the next 24hrs. The yellow line represents where the thunderstorms will be in general along with heavy rains. This region could see upwards to two inches of rainfall for some localized places. The red line outlines our area of concern for severe weather to include the possibility of tornadoes, this region will also have the chance of seeing upwards to four inches of rainfall. Now looking at the light blue line, this outlines our projected region that will see some sort of snowfall from the storm, not as heavy though. The darker blue region will be the area that could see upwards to six inches of snowfall. The purple line in the center is the area that could very well see upwards to 12-18 inches of snowfall from this storm.

Past 24hr Storm Summary: This storm system over the past 24hrs has been pushing out of the southwest and four corners region, bringing with it lots of snow to places like Colorado and also New Mexico; some of these places seen over one foot of snowfall. The rainfall has also been pushing through portions of southern Texas over the past 24hrs with some places getting some heavier rainfall.
24hr Storm Impacts: The next 24hrs this storm system is really going to become powerful as the center moves out into the panhandle of Texas. Once it arrives into the region, expect to see the severe weather start to increase in the warm sector, which will be lying right over the Gulf Coast region for most of the day on the 25th. The colder air on the back side which will stretch from northwest Texas into Oklahoma, and then eventually push into Kansas, will be the site for some places getting very heavy snowfall amounts. The heaviest snowfall band looks like it will setup over Kansas; here some places could see upwards to around one foot or more of snowfall before it’s all done. People along the Gulf Coast do need to be on the watch out for the severe weather as there is a pretty good chance we could be dealing with a few tornadoes and also wind damage and larger hail to hit the region. The end of this period will have the storm system finally pushing towards the northeast and the Great Lakes region by the 26th afternoon.
