The cycle continues … another round of weather ups and downs ahead

It’s becoming a bit of a broken record by this point, but
the cycle of ups and downs that have highlighted November’s weather thus far
will not be letting up in the week ahead.  After our last bout of rain brought some
impressive totals, and much needed as well, to the region – from 1 to as much
as 3 inches – we’ve now settled back into a period of high pressure, dry
conditions, and much cooler temperatures.  However, as with the last several weeks, the
mild weather’s return is not far off in the distance, and neither are our next
rain chances. In fact, it appears another extended period of wet weather is on
the way to the region for next week.
First, the cool temperatures still have another day or two
left to go, as readings have struggled to climb through the 50s today with a
light northerly breeze and crystal clear, sunny skies aided by very low
humidity levels.  These conditions will
set up a cold night tonight, with another freeze expected for most of the metro
area, including upper 20s outside the Memphis city limits. Southerly wind flow
will set back in on Friday, marking the start of a gradual warmup, though readings
will remain a bit below the mid-November average for one more day.
Breezy south winds Saturday will allow moisture levels to
increase, leading for increased mid and high level cloudiness, with
temperatures back well into the 60s. Meanwhile, a cold front will begin slowly
pushing southeast out of the Central Plains states, and it will begin impacting
Mid-South weather on Sunday.  Rain will
break out along and ahead of the front, and push through the region Sunday and
Sunday night. A few thunderstorms are possible as well, but with no severe
weather expected.
Very similar to the situation earlier this week, it appears
the front will then stall Sunday night just north of the metro area, across
Northeast Arkansas into Northwest Tennessee, and will remain nearby the area
through at least Tuesday. This will mean continued rain chances, with several
rounds of showers and a few thunderstorms possible. On Tuesday, a stronger
upper level disturbance will allow a low pressure area to develop and track
through the region, finally sweeping the cold front through by early Wednesday.
A final round of rain and thunderstorms is anticipated as this happens. Models
are still not in agreement on the exact timing and track of this low pressure,
which will ultimately determine if there is any threat of stronger
thunderstorms with this final round of wet weather.  Regardless, between Sunday and Tuesday, total
rainfall amounts of a few inches are certainly possible. With this week’s
rainfall, this may allow for some ponding and standing water issues to develop
in flood prone areas.
Weather Service surface weather forecast for Monday shows the stalled front
just north of the Memphis metro area, which will keep clouds and rain chances
in the forecast through Tuesday.
Fortunately, this system looks to exit the area just in time
for the Thanksgiving holiday, with a return to high pressure, drying conditions
and cooler temperatures anticipated. Those traveling on Wednesday currently
look to have no significant weather concerns to deal with, and Thanksgiving itself
currently looks sunny and seasonably cool.
look at the GFS model forecast for Thanksgiving afternoon shows nice weather
for the Mid-South and much of the country.
