100s Common in North Alabama. No Records, YET

Emily Maintains a Westward Course, Models More West with Her Track


Already the hottest day for many in the Tennessee Valley as the mercury has risen to the century mark and above. As of 2pm, Decatur, Muscle Shoals and Haleyville all were at 100. Several back-yard weather stations were also reporting 100+ readings: Athens 102, N. Courtland 100, Florence 102, Madison 103 and Hampton Cove 100.

A cold front will sliding southeast out of the Mid-Mississippi Valley towards the Tennesse Valley and was located near Bowling Green, KY-Hopkinsville, KY-surface low in southeast MO-then southwest through northwest Arkansas. Still had not noticed any t-storm develop in this vicinity but expect t-storm to develop through the evening hours in Kentucky and Tennessee and slide south towards the Valley itno the early morning hours, Thursday.

The boundary slides through the Valley during the early morning hours and becomes stationary just to the south of the Tennessee River. This will become the focus for additional storm development for the next several days as the boundary lingers about and some additional energy in the atmosphere also slides into the region.

The scattered storms that will be about will aid in lowering temperatures. Back into the mid and upper 90s for Thursday and then low and mid 90s for the weekend.

Now for Tropical Storm Emily. Emily. Emily has looked much more disorganized today. On visible satellite, her circulation has appeared in the open and well west of the main convective activity. A current hurricane hunter mission has located a new center about 123 miles SSW of Santo Domingo, DR with a minimum pressure of 1003 mb but the highest estimated surface winds appear to have fallen to around 40 to 45 mph. She continues to moves to the west (280 degrees) at 14 mph. The earlier modeling data would have had her beginning her northwest turn but that doesn’t appear evident, yet. 





As has been the case for the past several days, the Canadian and Navy NOGAPs continue to be tracking Emily more accurately and continue a more westerly track; however, the NOGAPS does turn her quickly northward from Jamaica over Cuba and into southeast Florida, near West Palm Beach, by Saturday morning. The newest suite of hurricane models jsut became available and here they are. Notice they are now also trending further west, again. Florida lies right in the middle of the spread.



I will stick to my gut forecast from several days ago and remain west and fine tune it once I see Emily begin jogging northwest.
