Tonight and Tomorrow... Weather conditions will remain quiet tonight
as near term guidance continues to show sfc high pressure just to
our northeast. HREF guidance is still showing low probabilities
(around 10-20%) of patchy fog development across portions of
southeast MS heading into early Sunday morning. Confidence is too
low to introduce any fog graphics at this time, however shallow fog
will be possible around dawn. Overnight lows will drop into the mid
to upper 60s areawide. Hot and dry conditions will persist across
our entire forecast area heading into Sunday afternoon. RHs will
drop to around 35-40% across much of our forecast area tomorrow on
Sunday. Meanwhile, areas across the NW Delta, including portions of
southeast AR, could see RHs drop below 30%. This combined with light
winds, could cause some low-end fire weather concerns. Afternoon
highs will peak into the low to mid 90s across our area. /CR/
Sunday Night through Friday...Despite ridging quickly building east
through the Lower Mississippi River Valley late in the period, the
overall troughing pattern will pretty much persist across the region
through the mid and extended portions of the forecast.  This, with
high pressure at the surface wedged into the region from the
northeast, will continue to promote quiet and continued hot
conditions across the forecast area through the week. A boundary
will try to approach from the west, but it`ll essentially stall and
washout before making it into the CWA.  Still, this could bring an
isolated shower or storm to mainly far northwest portions of the
forecast area Thursday and Friday afternoon. /19/
