898 FXUS64 KLZK 191110 AAA AFDLZK Area Forecast Discussion...UPDATED National Weather Service Little Rock AR 510 AM CST Sun Jan 19 2025 ...New AVIATION... .SHORT TERM... (Today through Monday Night) Issued at 243 AM CST Sun Jan 19 2025 The weak disturbance embedded in the mid-level flow will continue to track east away from the area this morning. Light snow/ flurries may continue for a few more hours before dry conditions return areawide. As clouds clear and dry air filters in, temperatures will efficiently fall through daybreak. Highs will struggle to climb into the 30s F across much of the state today. For Monday, a new H500 trough will approach from the NW. This will help usher in additional cold air as a robust area of surface ridging will be making its way down the Plains toward Arkansas. This setup will lead to largely dry conditions and very cold air. Winds will be lighter on Monday, but will still be active enough to influence wind chill values. && .LONG TERM... (Tuesday through Saturday) Issued at 243 AM CST Sun Jan 19 2025 TUESDAY: A positively-tilted trof axis will approach the state from the northwest on Tuesday. As this trof axis moves over the state a 100+ knot jet axis will be present at H500 from the ARK-LA-TEX region extending into the Tennessee River Valley. Arkansas will be in the left-front entrance region of this feature which promotes the sinking of air, thus equating to settled weather overall. The right- front region of the jet at H500 will be positioned over Louisiana and central Mississippi which will promote the rising of air and unsettled weather which may be in the form of wintry precipitation along the I-20 corridor and locations south. Expect overall fair and dry weather to persist over the state. A low possibility of flurries across far southern Arkansas (near the Arkansas/Louisiana border) will be possible, but will be a very low chance. Model trends continue to keep the appreciable amounts of wintry precipitation south of Arkansas. At the sfc, a high pressure center will be located in the Central Plains region of the CONUS with northerly winds at the sfc continuing to funnel in cold air keeping our low and high temperatures in the range of 15 to 20 degrees below average. WEDNESDAY/THURSDAY/FRIDAY/SATURDAY: In the upper lvls, northwesterly flow will be present over Arkansas on Wednesday. A second, upper lvl trof axis is progged to move over Arkansas into Friday. On Friday, at H500, another 100+ knot jet axis will be present with a similar position to the jet axis that was over the same region on Tuesday. Into Saturday, a slightly amplified ridge will move over the state equating to northwesterly flow aloft becoming southwesterly flow aloft on Saturday. At the sfc, a tandem of dry cold fronts will quickly move across the state during the day on Thursday and Friday. Despite the FROPA, cold air advection is not expected to be significant across the state as the air-mass behind these frontal boundaries will keep temperatures similar on Thursday and Friday. Expect fair and dry conditions to persist across the state. Sky conditions will vary from mostly sunny to partly cloudy skies over this four day period. Sfc winds will predominately be out of the west to southwest over this period with low and high temperatures remaining below average, but only by around 5 degrees by Thursday and Friday with temperatures increasing to normal values for late January on Saturday. && .AVIATION... (12Z TAFS) Issued at 508 AM CST Sun Jan 19 2025 Clouds across the eastern third of the state continue to quickly shift east which will give way to VFR conditions and mostly clear skies through the period. Winds will remain elevated through 20/00z generally out of the N/NW. Sustained winds in excess of 10 kts will be seen with gusts above 20 kts at times. && .PRELIMINARY POINT TEMPS/POPS...
