Two ways. First, the airmass overhead is gradually modifying as it is heated by the warmer ground. Second, and more important, the current cold air advection will switch to warm advection (lower-level winds off the Gulf) this afternoon. That should get our high above 40. May stay at 45 or less, but it should top 40.

It got down to 35.2 F here this morning. It hasn't warmed up much though, right now I'm showing 37.6 F.

I tried to tell you all that cold weather is bad. Wouldn't a nice, sunny 95 degree July day feel good just about now? Or maybe about 100 of them in a row... :lol:

The Canadian (GEM) continues to suggest an interesting pattern as we head into the weekend and next week. The coming weekend is looking rather damp and a bit warmer and then attention turns to our N and W. That model suggests ridging in the Pacific as well as a S dropping Polar Vortex into the Canadian Prairies. The Canadian also depicts a storm heading S along the Northern Canadian Rockies suggesting much colder air into spilling into the Lower 48. Something to watch in the days ahead. Guidance is struggling with the wave lengths across the Pacific and caution is advised when looking at the Operational guidance, IMO.

Ugh, 95 is miserable. I'd prefer 0 to 95. Ideally I'd like the temperature to be between 50 and 75 all the time. I still do like the colder weather though. :)

Cutoff low of to our W along the West Coast Pacific. The Arctic boundary is heading S prior to that feature moving onshore. While the Euro suggests the coldest air remains in Canada, there is enough coming S to create potential issues as wxman57 discussed earlier for areas further N. We shall see, but the models are still struggling with the mechanisms that could displace all that cold air building. Something to watch, IMO. Edit to add: Look at the Polar Vortex dropping S. That is one of the drivers as well as the Pacific pattern that will need to be watched closely as we head into the weekend. The Canadian is 'sniffing' that feature out as well.

Surface map (top right) doesn't appear to match the upper-level flow and known Arctic air in NW Canada. That is, there could be a bigger chunk of cold air moving south with the disturbance moving overhead. This would be a shallow layer of sub-freezing air that could result in an ice storm across the Southern Plains (to our north).

Both the 12z UKMET and Euro show strong ridging developing off the Pacific Coast at 144 hours. Could be that positive PNA showing its stuff and a prelude to more Arctic air into Texas?! ;)

I have a family event in Brenham on Saturday and a husband who is travelling to Austin (driving) on Monday. Will there be weather issues to worry about?

I am by no means a weather expert, but it just seems with all this cold air and some moisture - our area could luck out once and get some winter precip.

Thanks for everyone's input on the weather!!
