11/18 Long term

Forecast updated 3:45pm EST - 18 Nov 2011



Today's long term outlook includes an active weather pattern for the middle of the period when a frontal boundary stalls south of our region.  This will keep the best chances for precipitation across the south, however some rain showers could make it into our area for the Monday through Tuesday night time period.  This mornings GFS run puts the low pressure center over the southern Mississippi valley region by Tuesday afternoon with the associated rain showers across that area with some of the rain reaching the southern half of Indiana.

By Wednesday however this system is expected to be out of the region, bringing clear skies behind it.  These better conditions will continue through Thanksgiving Day as a large area of high pressure moves begins to dominate the pattern for much of the eastern US.  An associated upperlevel ridge across much of the country will provide for the development of a large thermal ridge and dry conditions to be the main story for the central US.  All of this making for good and rather typical fall-like weather for our region for the holiday.
