UPDATE. FOR 00Z AVIATION.
Visible satellite imagery this afternoon shows mostly clear skies, while just to the west upper level cloud cover continues to move in. Temperatures have been several degrees cooler today than 24 hours ago with temperatures in the 40's to mid 50's. As expected, mixing has allowed RH values to drop off into the 20-30 percent range.
Tonight . An upper level disturbance will moves through the Tennessee Valley while lower pressure drifts across the Gulf of Mexico. High pressure to the north will keep north winds in place and will continue to advect lower dewpoints into the area. Expect the atmosphere to remain to dry for any precipitation to make it this far north with this upper level wave. Overnight lows will be fairly similar to last nights.
Saturday will feature dry conditions as higher pressure at the surface continues to influence the region. Skies will gradually clear from west to east. North winds will continue through the day on Saturday. High temperatures on Saturday will range from the upper 40's to upper 50's.
LONG TERM (Saturday Night through Friday).
"Spring Ahead" is still over a week away, but that won't stop Spring from making itself felt next week. Temperatures will be climbing from near normal this Sunday upwards to 10-15 degrees above normal for Wed-Fri. The cause will be high pressure (surface to 500MB) that will be building over the area. So, not only will we be warming, we will remain mostly dry. Our dry surface dewpoints, which will heighten fire danger, will inch upward through Wednesday, until southerly winds finally humidify us more beginning Thursday. Isolated to scattered showers will be possible Thursday and Friday thanks to the increased surface moisture, in tandem with the steering flow pumping mid level moisture into TN as the 500MB ridge flattens.
1. Dry with no rain chances until Thurs-Fri.
2. Temperatures much above normal mid to late week.
3. Low afternoon RH values in the upper 20's to low 30's Sun-Mon will heighten fire danger, but winds will be fairly light.
AVIATION. 00Z TAF DISCUSSION.
A quiet overall TAF period is anticipated with VFR prevailing for the next 24 hours at all sites. A system will move to our south with the main result being continued northerly winds and increasing mid/high clouds overnight. Some SCT lower clouds are possible at CHA late tonight, but VFR ceilings will likely prevail. Generally northerly winds prevail tomorrow with largely clear skies.
. Low afternoon relative humidity will continues through early next week .
Dry northerly flow, both at the surface and aloft, will continue over the region through the weekend and into early next week. Very dry air will be in place aloft which, when combined with deepening mixed layers, will result in afternoon dewpoints and RH levels dropping off significantly. Current forecasts have afternoon RH values dropping into the 25-30 percent range in many places on Saturday, with only slight improvements into the low 30 percent area expected for Sunday and Monday. Surface high pressure shifts southeast of the southern Appalachians late Monday, with some degree of southerly flow returning to the area by Tuesday. This should provide some RH recover on Tuesday, with substantial rises by Wednesday. The silver lining in all of this is that winds are expected to be fairly light through the next several days.
