A slow moving frontal boundary stretching northwest to southeast across
the Northern-Central Plains into the Lower Mississippi Valley will
continue be the focus for active showers and thunderstorms over the next
few days. The next round of heavy rains to the east of this front
expected to form late Monday night into early Tuesday over the Central
High Plains across eastern Colorado and then push eastward early Tuesday
through Kansas and into western Missouri. This will be followed by yet
another area of potentially heavy rains Tuesday night into early Wednesday
from northeast Colorado, southern Nebraska into much of Missouri. With
the potential for more than one round of heavy rains to move across the
same regions, flash and river flooding will be possible from eastern
Colorado, across portions of Kansas and into Missouri.
In the regions of active thunderstorms over the next few days,
temperatures are expected to remain below average. Below average
temperatures and lower humidities will continue for the next two days
across portions of the East from the southern Mid-Atlantic into New
England. Above average temperatures to continue across the southern tier
of the nation from the Southern Plains, east across the Gulf Coast,
Southeast and Florida. While there is not expected to be many record
highs across these regions over the next two days, the hot temperatures
and high levels of humidity are resulting in heat advisories across much
of these regions, affecting nearly 37 million people.
Below average temperatures also on tap over the next few days for most
areas from the Rockies to the West Coast. Monsoonal showers and
thunderstorms possible from the Desert Southwest into the Rockies with
locally heavy rains and isolated flash flooding. Dry weather expected
along the West coast from California into the Pacific Northwest and the
Great Basin. This will continue the ongoing fire weather threat across
these areas, along with poor air quality from ongoing wild fires.
