NEAR TERM UPDATE /Now Through Friday/... An upper shortwave trough
will move across the TN valley region through the near term period.
Meanwhile, nearly zonal flow will be present aloft across the
northern Gulf by Thursday morning. At the surface, a cold front
continues advancing southeastward across the CWA into the morning
hours before stalling sometime early Thursday morning along the I-65
corridor. With some forcing still present ahead of the advancing
front, a chance of rain showers and a potential isolated
thunderstorm cannot be ruled out overnight. Additionally, model
guidance is indicative of patchy fog development out ahead of the
front with the greatest chance occurring in the south portion of the
CWA. The chance for fog development will begin to decrease into the
mid-morning hours on Thursday. Lows tonight are expected to be
coolest behind the front with temps ranging from the mid 50s to low
60s north of I-65, and low to upper 60s south of I-65 ahead of the
front. High temps on Thursday are expected to be in the low to upper
70s north of I-65, with upper 70s to around 80 degrees south of I-

With the front remaining stalled along the I-65 corridor, rain
shower chances still exist through Friday morning ahead of the
frontal boundary. By Friday afternoon, an approaching shortwave
trough aloft quickly advances into the area bringing increased rain
chances Friday afternoon into Friday night. An upper level jet also
begins strengthening in response across the ArkLaMiss region
bringing some upper level divergence aloft across our region. Thus,
will continue to show rain chances increasing to the likely range
over the western and northwestern portion of the CWA into Friday
afternoon and spreading across much of the forecast area Friday
night. Low temps Friday morning are expected to be similar to
overnight lows tonight, possibly a few degrees cooler in some areas.
High temps are expected to be a few degrees cooler than what is
expected on Thursday ranging in the low to upper 70s across
the region. JEH/88
