Area forecast discussion National Weather Service Jackson MS 945 am CST Friday Nov 21 2014 Update...high pressure across the Ohio Valley will push slowly east today allowing southerly flow to continue. This will slowly increase temperatures and dewpoints through the day. Have made the usual adjustments to the temperature and dew point trends but highs look good. Also...trimmed back small shower chances in our western areas a few hours but kept in for this afternoon. We will continue to evaluate the parameters for the system expected to impact the area Saturday night and Sunday morning. There still appears to be a window of opportunity for severe weather between approx 3am and noon Sunday. Also...will evaluate the potential for Sunday to be windy particularly in the southern portions of the forecast area. /SW/ && Aviation...VFR conditions will prevail this taf period with some mix of middle level clouds across the west and then spreading over the area later tonight. As we approach midday Sat...some low end potential will exist for MVFR ceilings...but will not include in the new set of tafs at this time. /Cme/ && Previous discussion... /issued 431 am CST Friday Nov 21 2014/ Short term...today through Sunday...the story for the short term continues to be the potential for severe storms Saturday night. High pressure will continue to prevail over much of the area today and with southerly flow the warming tend will continue with highs in the middle/upper 60s. With the better moisture along and west of the Mississippi River a few showers will be possible this afternoon over those areas. Little will change tonight with a few showers possible in the far west and slightly warmer overnight lows in the middle/upper 40s. A very strong Pacific jet will dig out a deep upper trough and drop down into The Four Corners area Friday night into Saturday. Moisture will increase across the area Saturday afternoon into the evening hours out ahead of this system with precipitable waters climbing to 1.7-1.8 inches by late evening. The models have been slowing this system down the past few runs and by Saturday afternoon the negatively tilted trough will extend over central Texas with an associated surface low/frontal boundary. The models are in pretty good agreement on the timing of the system across the area Saturday night into Sunday morning. The wind shear with this system is impressive...but the big question continues to be the amount of instability with the system as it crosses the arklamiss. Both the GFS/European model (ecmwf) are showing around 100-300 j/kg of ml cape mainly over the southern portions of the area. The h700-h500 lapse rates are not to impressive either ranging from around 5.5-6.0 c/km. The latest run of the cips analog indicates the potential for severe across most of the area...so will leave our current risk areas with the greatest potential for severe along and south of I-20. The storms will shift east of the area by middle morning on Sunday with a few remnant showers possible in the east until early afternoon. Drier air will build in quickly Sunday afternoon with precipitable waters falling below an inch by early evening. The GFS/European model (ecmwf) indicate h925 temperatures around 18c on Sunday and this translates to very warm temperatures on Sunday with highs in the middle/upper 70s. Long term...Sunday night through next Friday... A dry and cooler pattern is in store for the arklamiss Thanksgiving week as a western ridge and eastern trough pattern sets up and brings dry northwest flow aloft. Expect surface temperatures to be 5-10 degree f below normal for the most part. Cips shows substantial negative temperature anomalies...but this polar airmass will not be nearly as cold as the recent Arctic air outbreak. It appears the next significant chance for rainfall may not materialize until the first week of December. /Ec/ && Preliminary point temps/pops...
