Rain Chances: Parade of Lows

Pattern Changing: Rain Chances Improving

6 February 2009

For much of the winter, there has been an upper trough in the east and a ridge in the west, which has kept us generally in a dry flow aloft. Now, the scene seems to be transitioning into a flow studded with upper lows (see map). Such a flow generally brings a greater number of upper troughs over Texoma, which favor a greater number of rain events.

Another aspect of this change is the surface wind flow. Dry polar air would “sweep out” much of available Gulf moisture ahead of approaching systems; so when fronts did pass they were usually dry.  The surface wind flow should moisten up as polar air stays out of the Gulf for a while.

Take Care,

    i have a question, is there a chance of tornadoes, or severe weather?

    Steve, great news but I have a question. By "favor a greater number of rain events" would that be a greater amount than what is normal for this time of year or greater than we have seen over the last 6 months? Do you anticipate this increase to run into the spring or just the next couple of weeks?
