UPDATE. For 12Z Aviation.

SHORT TERM. /Updated at 0146 AM CST Mon Jan 20 2020/ Through Tonight.

It will be a cold day out there today, with a northerly flow keeping temperatures in the 30s and 40s for highs. Tonight we will see a quick moving disturbance slide through and provide just enough lift to squeeze out some snow flurries across the northern half of the area. Most of the snow flurries will be falling from 6 to 10 thousand feet and through a very dry layer near the surface, so very little will make it to the surface at all. So that it will not catch anyone off guard, continued to to mention the flurries in the forecast after midnight through sunrise Tuesday. Due to the clouds, the temperatures will only drop into the low to mid 20s.

LONG TERM. /Updated at 0227 AM CST Mon Jan 20 2020/ Tuesday through Sunday.

An upper low will move to the Georgia/South Carolina coast on Tuesday, while shortwave ridging builds in from the northwest. Dry northwest flow will quickly remove any lingering flurries, with skies clearing by mid-morning. Northerly winds associated with high pressure building into the Ohio Valley will keep highs in the low to mid 40s. The pressure gradient begins to relax somewhat Tuesday night as the center of the high reaches the central/southern Appalachians, and winds will go calm at sheltered locations allowing for favorable radiational cooling conditions before cirrus move in from the west later in the night. Will continue to go on the cooler side of guidance with lows in the low 20s, with some teens possible in typically colder locations. A fairly weak longwave trough moves into the central CONUS by Wednesday, while the surface ridge axis will be located along the East Coast to the west of low pressure over the western Atlantic. Temperatures on Wednesday will be milder than previous days, but will be tempered by an easterly component to the surface winds, and mid and high level clouds will increase through the afternoon. Mid and high level moisture continues to increase Wednesday night, and mid-level isentropic lift will result in the potential for virga as well. However, at this time the air mass below 600mb is expected to be too dry for any hydrometeors to make it to the surface Wednesday night. Cloudcover and east winds should keep temperatures milder Wednesday night.

Within the approaching long wave trough, a southern stream shortwave will move through the area Thursday afternoon/Thursday night, while a southeastward moving northern stream wave closes off into an upper low over the Ozarks Thursday night. In general there will be two surface lows, one associated with the upper low that moves into the Ohio Valley, and one that develops along the Gulf Coast and moves up the East Coast eventually becoming a nor'easter. There continues to be some discrepancies regarding details regarding these lows. But regardless, expect increasing rain chances during the day on Thursday with high rain chances Thursday night. Models continue to trend quicker with the onset of precipitation and future updates may need to increase PoPs sooner. PWATs will be only an inch or less, and rainfall amounts should only be around a half inch to an inch, limiting flooding concerns. Models differ on whether the warm sector will make it this far inland, but even if it does theta-e return appears insufficient for any appreciable instability to develop and will continue to leave thunder out of the forecast. The system exits off to the northeast on Friday though some wraparound low-level moisture could linger into Friday night depending on the track of the upper low. Northwest flow moves in for the weekend. A shortwave approaches on Sunday, but confidence in available moisture is too low to mention any PoPs at this time.

AVIATION. 12Z TAF Discussion.

Overall VFR conditions expected for the next 24 hours. There will be a disturbance that slides through the area. This will supply mid to high clouds to the area as well as moisture aloft. There could be some snow flurries across the area but they will fall into a dry airmass in the lower levels, thus no impact is expected as ceilings remain above 7000 feet and visibilities remain 10sm.

FIRE WEATHER.

A change in the weather pattern will continue today through the middle of next week with cooler and drier conditions expected. Relative humidity values will fall into the 30s this afternoon and Tuesday afternoon with north-northwesterly winds, and into the 20s in some areas Wednesday afternoon with lighter winds, but red flag criteria will not be met for these parameters. Additionally, KBDI values remain less than 100 due to recent wet conditions.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
