The warm front looks as if it will push farther NE than expected yesterday. This has lead to a larger area of severe risk. New Discussion:
-There will be three focal points for severe weather today. A warm front, a dry line, and a cold front. Here is the warm front discussion:
-A warm front will lift NE throughout the day today. It is currently located along the LA/AR border and will be lifting NE. North of the warm front, the air mass is not all that warm and unstable, but south of it, it is. So, it looks like throughout the day storms will be firing along and south of the warm front, and move north of the warm front. An enhanced area of jet energy will be moving along and south of the warm front today. This will be where the first area of big storms will likely develop. It will likely begin to get active along this feature in AR/N.Louisiana/E Oklahoma. Super cells with potentially huge hail due to CAPEs of well over 2000, LIs of less than -8, DPs in the 70s, and hot temperatures will occur. Also tornadoes will be a very large threat, along with damaging winds. It will shift east into eastern AR, SE Missouri, and western TN late this evening which is when conditions will be best for tornadoes. I believe this area is where we could have some large, damaging tornadoes. The threat will shift into the SE tonight as this little jet stream feature pushes east. This severe weather may organize into a derecho as it pushes east late this evening. Either way the high severe threat will linger throughout the night
-In the warm sector along the dry line and the cold front that will catch up to it, instability will be extreme along with very high dew points, and a strengthening jet stream. This will cause super cells to develop in the warm sector, with a lot of them focused along the dry line/cold front to develop late this afternoon. Tornadoes will be a threat but not as big of one as in the areas I mentioned above. Huge hail will also be a big threat. As the evening goes on damaging winds will be a growing threat, as it appears that late this evening the storms will organize into a large squall line along the cold front, with a continued hail threat and a high damaging wind threat. This squall line will push ESE very quickly tonight along the cold front.
-More updates later.
