.DISCUSSION...
underneath a much broader area of higher pressure aloft. Today
will be a carbon-copy of yesterday, but tomorrow we can expect
increasing cloudiness as Tropical Storm Beta makes landfall and
begins to push moisture northeastward into Middle Tennessee. Beta
will exhibit little movement afterwards. Both the GFS & Euro
models show the low center eventually dissolving near the Gulf
Coast by mid-week, but a great deal of its residual moisture will
get picked up by a developing upper trough that will come through
Thursday and Friday and bring our next round of showers. A second
system will come through Middle Tennessee during the weekend and
keep high rain chances in the forecast at least through Sunday.
Given the warm temperatures expected Saturday and Sunday along
with ~70F dew points, we`ll include a mention of thunder those
two days. Still, no hazardous weather is anticipated. Storm total
QPF through Sunday night gives us a multi-day total ranging from a
little over an inch around Land-between-the-Lakes to nearly 3
inches across parts of the Cumberland Plateau. But coming off a
dry spell that has lasted more than a week, don`t expect these
amounts to produce excessive runoff. A strong fropa next Sunday
night will drop temperatures back to normal readings by early next
week.
