Will Remnant Moisture From Tropical Storm Fernand Affect Our Weather?

A persistent ridge of high pressure at the mid levels of the atmosphere has dominated our weather of late. This ridge in part has been responsible for the excessive heat and drought this summer locally.

A pattern change continues to be forecast by the computer models especially the GFS starting this weekend. It is rather optimistic with a trough of low pressure diving southeastward out of the Pacific Northwest and into the western and central Rockies. This is important because at the same time the remnant moisture from now Tropical Storm Fernand located well south of Brownsville, Texas is forecast by this model to get swept up and pulled northward into northern Mexico and the local area.

The European model is much less optimistic concerning all of this and keeps us drier and warmer. So the battle of the models continues. I will note that the track record of the GFS models forecasts of late are less than impressive. Reality may be somewhere in the middle of these two model forecasts this weekend into next week.

There is nothing unusual about a trough of low pressure pulling remnant moisture up into the area this time of the area. It happens all of the time. Hopefully the models are on to something and we are fixing to cool off and get a lot wetter.
