Keep The Rain Gear Close By

From Meteorologist Brandon Rector...

We are starting off with a range of temperatures across the viewing area this morning. Temperatuers bottomed out anywhere from the upper 30s to upper 40s. Fog has developed once again as well. It will be dense in some locations. Please take your time getting to your destination this morning and use your low beam headlights. We weren't the only ones dealing with dense fog to start the day. A Dense Fog Advisory stretched from our eastern counties all the way to Louisiana and Arkansas. A Dense Fog Advisory is issued when visibilities will be a quarter of a mile or less. As if the fog wasn't enough to deal with this morning, we also had some showers move through as well.

The fog should clear by the mid to late morning hours. We will continue to see mostly cloudy skies. The chance for more isolated showers will also continue at 20%. Highs today should be in the low 60s.

The chance for rain increases tonight through Friday to about 30% to 40%. We may see some isolated thunderstorms during this time period as well. The reason for the rain is because of two features. One, a cold front moved through the area and will stall out to our south. Gulf moisture will ride over this cooler air mass and possibly cause some rain. This process is something we call isentropic lift. We also have the southern branch of the jet stream moving through the state. This will bring in Pacific moisture in the mid and upper levels of the atmosphere. Upper level disturbances will ride this jet stream into our area and possibly bring us some rain. Some models are showing total rainfall amounts for the next three days in the half inch to inch category. I feel these models are overdoing it. I think we will only end up with a quarter of an inch to a half inch. Keep you fingers crossed. Anything we get will be better than what we have received lately, which is pretty much nothing. Temperatures for Thursday and Friday should be in the upper 50s.

The colder air that was expected this weekend doesn't look like it is going to make it now. That air looks to remain to our north and east. I have increased our highs to the low 60s for Saturday and Sunday. We should begin the drying out process druing that time too.

By early next week, skies clear out and temperatures will return to well above average levels. We could see highs back in the low 70s by Tuesday.

Have a wonderful Wednesday!
