...Excessive heat is expected for the Desert Southwest, across the
mid-section of the country, while heat and humidity continue over
parts of the Northeast...

...Showers and thunderstorms could become severe from the central
Plains to the Midwest for the next couple of days...

A summery weather pattern is expected to continue for the next
couple of days as above normal temperatures are forecast for much
of the U.S.  In fact, excessive heat warnings are scheduled to
take into effect for much of the Desert Southwest Tuesday and
Wednesday, as afternoon high temperatures are forecast to soar
into the record-setting 110's on Wednesday.  Heat advisories and
excessive heat warnings are also in effect for a large area across
the mid-section of the country.  In addition, a heat wave will
continue from the Mid-Atlantic into New England as well.  North of
the heat and humidity, some cooler air from Canada is spreading
south and eastward into the northern Plains.  Showers and
thunderstorms will be the focus along a slow-moving frontal
boundary across the central Plains toward the Midwest for the next
couple of days.  Some of these thunderstorms are expected to
become severe.  Strong to severe thunderstorms are also possible
through this evening over parts of the Northeast.

Along the Gulf Coast into the southeastern U.S., lingering showers
and thunderstorms are expected to continue into Wednesday, where
some heavy downpours are possible.  By contrast, low humidities
and gusty winds are expected to create elevated fire weather
conditions for much of Wyoming.  Elsewhere, dry conditions will
prevail for the rest the western U.S. through Wednesday.
