As we have seen recently winter is well on its way. The National Weather Service has issued a statement regarding the effect of El Nino on this years’ winter weather. The Weather Service has predicted that El Nino will strengthen as we ease into winter. This will cause the Southeastern sector of the U.S. to see [...]
Although temperatures have been on the chilly side, it has been a beautiful day across the area. The low in Tuscaloosa was 36 degrees last night and we will be dropping into the mid 30s again tonight. The sky will be clear, with another bright blue sky tomorrow. A strong 1025 MB high over the [...]
A good Sunday to you! After temperatures reached the upper 30s lastnight, we moderated into the low 60s this afternoon. With the brisk north wind, it still feels chilly. Winds will go calm this evening and tonight, which will set the stage for a very cold night. All of Alabama is under a frost advisory, [...]Cold weather is the big story for the rest of the weekend, as we feel the coldest temperatures so far this season. Much of the WVUA-TV coverage area is under a freeze watch for Sunday night. Temperatures are expected to get close to freezing, and as winds go calm, we will deal with some frost. [...]
With another week of rainy weather, a few rivers have climbed above flood stage. Luckily, the weekend and the first part of next week is expected to be dry. The latest river stages are shown in the graphic below.

Since the big digital switch, WVUA’s new powerful signal reaches a much larger audience. I am proud to welcome our new viewers on the Charter Cable system in Birmingham. A big UA homecoming weekend is here and for Alabama fans rolling into town, brace for cold weather. All across West Alabama, temperatures today have been [...]I want to remind you about a National Weather Service spotter training course that will be taking place tonight at the old fire college across from Brunos on McFarland Boulevard. A big thanks to the Tuscaloosa EMA and the NWS for making this happen. We’re working to have another severe weather seminar at the University [...]

Take a look at the latest high-resolution 4 km WRF 24h precipitation ending Friday and Saturday at 5 PM . A plume of moisture associated with a Pacific front will slowly move southward over the region . Black indicates 2-5 inches over 24h . Both the SW Olympics and the central Cascades get hit fairly hard .

Nice rainshadow NE of the Olympics . The front moves through later on Saturday and Sunday bringing showers and a strong convergence zone north of Seattle .

A fairly strong cold front followed by rapidly increasing pressure will push into eastern Washington tomorrow . with several pulses of cold air and high pressure over the weekend . Take a look at several forecast charts over the next few days--they show sea level pressure , surface winds , and temperature with blue being cold Notice how the cold colors push in as the cold front moves southward . This surge of cold air will cause fairly strong winds from the north and northeast . but not as strong as last Sunday . Winds will surely reach 20-30 mph , with some stronger gusts--and such winds are strong enough to raise . dust The problem is that many farmer's have tilled the soil in preparation for next season , and the ground is very dry .

Such a system would be essentially probabilistic in nature---rather than giving a single answer as we do today . It really doesn't make sense to say the high temp at Seattle in seven days will be 67F--there is substantial uncertainty in the answer and that uncertainty depends on the situation . My field is developing the technologies to provide uncertainty information--including probabilities of much more than precipitation . This is a major revolution in the way we do business . But is the population ready for this Will they accept and use it While I was in Boulder it snowed On Wednesday , there were snow flakes in the air , with temperatures dropping into the upper 30sF . Being over 5000 ft and open to the cold air to the north really . helps This weekend will be moderate in temperature and very nice here in the NW .
