Area Forecast Discussion National Weather Service San Angelo TX 1152 AM CST Wed Feb 1 2023 ...New AVIATION... .SHORT TERM... (Today through Thursday) Issued at 338 AM CST Wed Feb 1 2023 ...Significant Icing Event Likely Today and Tonight... An Ice Storm Warning is in effect today and tonight for all of our counties except Kimble, Mason and San Saba, where a Winter Storm Warning is in effect. Area radars show increased coverage of mainly light freezing rain, extending from the Big Bend northeast across West Central Texas early this morning. This is associated with increased ascent out ahead of an upper low, centered over Baja California. A shallow, cold airmass is entrenched across our area with temperatures in the mid to upper 20s. With moisture overrunning this shallow, cold air along with mid/upper level moisture overspreading our area associated with subtropical branch of an upper level jet, precipitable water values will increase to 0.8 and 1 inch across our area this morning. With the column becoming saturated, heavier freezing rain is likely today as ascent continues ahead of the upper low as it tracks east- southeast into Sonora Province in Mexico. Some sleet could occur in our central and northern counties, mainly this morning until the subfreezing layer decreases beneath the warm nose aloft (per forecast soundings). The primary concern, however, is with ice accumulations from freezing rain. With the shallow, cold airmass rather slow to moderate, temperatures will remain below freezing today, climbing to the upper 20s to around 30 for highs this afternoon. Ice accumulations of one quarter to one half inch are possible, with some places probably seeing less than this. The more widespread freezing rain coverage will worsen conditions where ice already exists, and will cause very hazardous conditions for motorists and pedestrians across West Central Texas with ice on roads, sidewalks, bridges and overpasses. A few power outages and damage to trees will also be possible due to the ice accumulations. Some additional freezing rain is expected tonight, with the approach of the upper low from northern Mexico. The intensity and coverage should be less than what occurs today, but would only lead to overall worsening of conditions as temperatures stay below freezing (dropping a degree or two). Conditions will finally start to improve on Thursday. The upper low will open into a trough and move east across our area during the day. Some light rain or freezing rain is possible early in the morning, prior to 10 AM with temperatures around the freezing mark. Temperatures will then climb above freezing, reaching the upper 30s east to lower 40s west for highs Thursday afternoon. These collaborated forecast highs are several degrees below blended guidance, which has been consistently too warm with our temperatures in the past few days. Isolated to scattered showers (liquid form) will be possible, but rain chances will diminish from west to east in the afternoon as the upper trough axis moves east across the area. Our area should have a decrease in cloud cover from the west in the mid-to-late afternoon. && .LONG TERM... (Thursday Night through next Wednesday) Issued at 338 AM CST Wed Feb 1 2023 Skies should clear by Thursday evening as the axis of a 500mb trough pushes eastward. As a result, low temperatures will fall back into the 20s. This means road conditions could still be icy on Friday morning due to any re-freezing taking place. Confidence is high at this point that we will see a gradual warming through the weekend as a quasi-zonal pattern sets up with southerly surface flow. By the early to middle part of next week, long-range models indicate a trough dropping into the central US from the Pacific Northwest. However, models differ greatly on how far south this trough will dig and how it will evolve. For now, some minor rain chances were included for Tuesday night into Wednesday of next week, with highs generally around normal for this time of year. && .AVIATION... (18Z TAFS) Issued at 1142 AM CST Wed Feb 1 2023 Freezing rain and sleet are expanding in coverage mainly north of the I-10 corridor early this afternoon. This activity will continue to impact primarily the KABI and KSJT terminals through much of the afternoon and evening hours. Ceilings will lower to MVFR/IFR with reduction in visibilities where the heavier bands of precipitation fall. The southern terminals (KSOA and KJCT) will be less impacted by the freezing/sleet this afternoon. && .PRELIMINARY POINT TEMPS/POPS...
