Area forecast discussion National Weather Service Jackson MS 430 am CST Sat Dec 20 2014 Short term...today through Sunday night...with the exception of our southeast...a dry weekend is expected. Early morning surface analysis had a ridge just to our northwest emanating from a high centered over the northern Great Lakes region and a low over the northern Gulf just southeast of the Louisiana coast. Water vapor imagery/RUC analysis showed a shortwave trough nearing our Delta Region that will swing east of Mississippi by noon and help keep the Gulf surface low tracking east. This will help end the remaining light rain that was falling over our southeast zones. Dry weather is expected today for the remainder of the County Warning Area. The drier air aloft in the wake of the shortwave and the low level dry north to northeast flow from the surface ridge should help the sun to break through from the north this afternoon. Despite some insolation temperatures are still expected to top out cooler than normal and generally in the low to middle 50s. Tonight will be cool and dry with our sites in the northeast bottoming out near freezing Sunday morning. The surface ridge will remain over our County Warning Area Sunday while our winds aloft back to the southwest ahead of the next approaching shortwave trough. This shortwave will swing across the area Sunday night and support another surface low over the northern Gulf. Models suggest a low potential of light rain chances over our southeast zones Sunday night. Model consensus tracks this weak surface low a little farther south than the current surface low tracking over the Gulf this morning. The dry east flow around the surface ridge Sunday will limit return flow until Sunday night when it weakens. This in turn will limit rain chances and quantitative precipitation forecast amounts in our County Warning Area Sunday night. /22/ Long term...Monday through Saturday...looks like a pretty active long term forecast for the arklamiss. Monday looks like it will be mostly dry across the area with precipitable waters generally less the .75 inches across the area. Moisture will be on the increase Monday night out ahead of a deepening upper trough over the plains and associated cold front. Showers will be on the increase early on Tuesday out ahead of the system with thunderstorms developing during the day. There is some timing differences between the models and also the models differ on the track of the surface low. The European model (ecmwf) has shifted the surface low track a little to the east and this will allow the best instability/shear to be east of the area while the GFS is a little further to the west. The NAM is a little slower with the boundary and indicates 400-600 j/kg of ml cape along with a decent amount of shear. 0-3 helicity values range from 220 in the west to 340 m^2/s^2 in the east. Due to these reasons along with severe cips analogs lining up with this event...will introduce at least a limited risk of severe in the severe weather potential statement/graphicasts for Tuesday. The cold front will shift to the east of the area and surface high pressure ridging will build in on Wednesday. A cool day is on tap with highs topping out in the 40s across much of the area. The high pressure system will shift across the northern Gulf and the flow will once again swing around to the south early on Thursday. Expect a warmup to begin as upper ridging briefly builds across the area before another strong upper trough depends over the plains. Moisture will begin to increase across the area on Friday with another chance of showers/thunderstorms. The European model (ecmwf) has been the more aggressive model for the potential for severe once again late in the week...while the GFS is not as deep with the upper trough and is weaker with the cold front. Both of the models build high pressure into the area on Saturday./15/ && Aviation...a surface low tracking east over the northern Gulf was helping produce light rain over southeast MS and widespread IFR ceilings over the southern half of MS early this morning. This low will track east today and conditions will eventually improve from the northwest later this morning. MVFR ceilings may persist until 18z over mei-hbg. VFR conds are expected by middle afternoon and will continue tonight. /22/ && Preliminary point temps/pops...
