LONG TERM [Wednesday Night through next Monday]...
The long wave trough will be exiting the area to the east at the
start of the period followed by a short wave ridge on Thursday. A
short wave will sweep by well to our north on Friday and that will
be followed by a period of mainly zonal flow aloft through the
weekend. Surface high pressure will generally be in control
through this period. Therefore, benign weather is expected to
continue through the weekend with all POPS below 15 percent. MIN
temperatures will be a FEW degrees below NORMAL through the period
with highs near seasonal levels Thursday and Friday before
dropping below normal for the weekend. By Monday, return flow will
commence as high pressure moves east. A frontal system will be
moving into the Lower MS Valley and slight CHANCE PoPs are
included for Monday.
