The parent trough that brought us the showers last night has since lifted well of to our north and east this morning. However, the base of the trough still is close enough to our area, and when combined with subtle PVA remaining, some clouds are hanging around and will likely persist through the overnight hours. However, they are certainly not widespread and we've got about a 95% blue, sunny sky!
High pressure is forecast to be right on top of us tonight. With efficient radiational cooling and calm winds, temperatures will bottom out in the mid 30s for most locations. But, I wouldn't be surprised to see some areas of north-central Mississippi get close to the freezing mark!
By tomorrow, the GFS is forecasting more of a flat ridge in place across the area with a piece of energy associated with the subtropical jet over the Gulf of California. Friday should be a nice, sunny day with moderating temperatures with highs in the 60s; it should feel fantastic!
By Saturday, despite a very dry low level airmass, some mid-level PVA associated with the aforementioned piece of energy in the Gulf of California will bring us some clouds by Saturday, but no rain is expected thanks to the dry surface airmass.
The GFS is forecasting a fairly strong long wave trough over the eastern half of the country by the first part of next week. Because moisture return will be weak, albeit nonzero, we probably can squeeze out a few showers but for now, no widespread rain is expected.
Looking ahead past this trough, the NAO is forecasted to go mostly negative once again. The Euro and GFS both suggest very strong high pressure associated with a rather cold airmass by the middle and end of next week, which would support this negative NAO forecast. Some of the raw temperature guidance suggests we'll be well down below freezing into the 20s! Brrrr! We'll watch things, stay tuned!
