A strong cold front moved through East Texas last night and you can tell, much colder air has moved in. The winds today will still be quite gusty out of the northwest around 20 to 25 miles per hour through the early afternoon hours. As the Canadian high pressure mov0se over East Texas late this afternoon, our winds will die down setting the stage for a very cold evening. By 10PM winds will more than likely be below 5 miles per hour in most areas with the exception being our higher ridge tops across East Texas. In the areas where the winds are below 5 miles per hour, temperatures will rapidly drop. At the same time dew point temperatures, or the temperature at which dew forms on objects, will be well below freezing, in the lower 20s in most areas. This will allow for any moisture that forms on outdoor objects to quickly freeze causing frost to develop. So if the winds do die down early enough most of East Texas will wake up to a frosty start on our Friday. If the winds do not die down below 5 miles per hour, wide spread frost will not form but I would still bring in any tender vegetation you may have.
With much of East Texas expecting frost tonight, some parts of East Texas could experience freezing temperatures towards morning. Again this all depends on the wind speed. With light winds temperatures are allowed to drop very rapidly and can approach the dewpoint. I would not be surprised if a few of our normally cooler locations in the morning dropped to near 30 degrees, possibly even the upper 20s. Freeze warnings have been posted for our northwestern counties but if it looks like the winds will die down early enough, those warnings may be extended farther south and east.
