11/1 – Brittany’s “Well above Seasonal Conditions” Tuesday Evening Forecast
Upper level moisture/clouds continue to stream through the area in advance of a weak upper level disturbance moving NE. The disturbance will move northeastward and deamplify, with most of the moisture with this system above 10,000’. Thus, mainly mid and upper clouds expected tonight, with a few spotty showers possible through sunrise.
Upper high pressure will gradually build over the north central Gulf of Mexico through the end of the work week. A strong disturbance will lift northeastward from the southern Rockies into the middle and upper Mississippi River Valley Friday and Saturday. The best upper support is expected to be well to the north and northwest of our area, but the disturbance will suppress the strongest high pressure east of the area by the end of the weekend. Likely to be a fairly sharp gradient of precipitation chances from west to east across our area. The best chances of rain, such as they are, will be over western portions of the area on Saturday. It’s entirely possible that areas east of Interstate 55 see little or no precipitation this weekend.
Much above normal temperatures expected through the forecast period, with high temperatures 10 degrees F or more above normal in many areas. Overnight lows likely to be 10-15 F above normal as well, with no significant cooling expected prior to the middle of next week, if that soon.
