The unrelenting summer of 2023 heat wave will continue in earnest across
the southern tier of the nation from the Southwest, through Central to
South Texas and along much of the Gulf coast, including Florida, as the
new work week begins.  Numerous record high temperatures and record high
morning minimum temperatures are likely over the next few days with no end
in sight going into the later part of this week.  Excessive heat warnings
and heat advisories are currently in effect across all of the southern
tier of the nation from southeast California into Florida and will likely
remain in effect for the foreseeable future as there is no relief in sight
to the heat for the remainder of the week across these areas.

In addition to the hot temperatures across the southern tier of the
nation,  there will continue to be an elevated fire weather risk across
portions of the Southwest into the Southern Plains.  Dry conditions, low
relative humidities and gusty winds will continue to support the fire
weather threat across these areas.

A very active thunderstorm pattern is expected over the next few days
across large sections of the nation to the east of the Mississippi River. 
In the areas of thunderstorms, severe weather and flash flooding will be a
threat.    Active showers and thunderstorms expected to continue from
Sunday afternoon into Sunday evening from the Mid-West into portions of
the Great Lakes, Mid Atlantic and into the Southeast.   This active shower
and thunderstorm pattern will then again re-intensify Monday afternoon
from the Ohio Valley into the Appalachians and along large portions of the
east coast from the Southeast into the Northeast.  These active areas of
storms are associated with a strong area of low pressure and its
associated cold front expected to press eastward across large portions of
the nation to the east of the Mississippi River over the next two days.

A separate storm system pushing inland from the northeast Pacific into the
northwestern portion of the nation will support increasing shower and
thunderstorm activity Monday from the inland regions of the Pacific
Northwest to the east of the Cascades and eastward into the Northern
Rockies.  Heavy rains and isolated flash flooding are possible, with flood
watches currently in effect from northeast Washington State into northern
Idaho.
