...An October heatwave will remain across central and southern
California through mid-week...

...Autumnal chill lingers for the Great Lakes and Northeast behind
a cold front...

...Heavy rainfall and isolated flood threat persists in Florida...

A dangerous October heatwave continues for portions of California
and the Desert Southwest into mid-week. High temperatures remain
15-20 degrees above average with highs reaching into the 90s to
low 100s and overnight lows in the mid- to upper 70s providing
little relief from the heat overnight. This heat has led to Heat
Levels of Major to Extreme (Levels 3 and 4 of 4) particularly
along coastal California indicating a level of heat dangerous to
anyone without adequate cooling or hydration. Temperatures are
expected to gradually cool for coastal California Thursday and
then interior areas Friday-Saturday so some relief from the heat
is in sight. While not dangerously hot, conditions across the
western to central U.S. remain well above average for October with
widespread highs in the 70s and 80s. Some daily
record-tying/breaking highs will be possible. On the other hand,
conditions remain cooler and below average along the East Coast
and particularly for the Northeast through today (Tuesday) with
highs mainly in the 50s and 60s. Frost and Freeze related
Advisories and Warnings are in place for much of New England as
well as portions of the northern Mid-Atlantic Wednesday morning as
temperatures are forecast to fall into the 30s. However,
temperatures will moderate quite a bit over the next couple of
days with much warmer highs into the 70s expected for most
locations by Thursday. 

Gulf moisture pooling along a quasi-stationary boundary through
Florida will continue to lead to widespread thunderstorms across
most of the Florida Peninsula and parts of the Panhandle and
southeastern Georgia coast the next few days. Locally heavy
downpours may lead to a few inches of rain each day with some
isolated flooding/ponding possible particularly in urban areas.
Some thunderstorms and locally heavy downpours will be possible
for far South Texas near the western end of the boundary as well.
Otherwise, the rest of the country will be mostly dry through
mid-week with only some widely scattered showers expected over the
central Rockies/Four Corners region and with a frontal system
moving through the Upper Great Lakes into the interior Northeast
late Wednesday into Thursday. Newly formed T.D. Nine is forecast
by the National Hurricane Center to bring impacts to the Gulf
Coast/Southeast later this week and into the weekend just beyond
the current forecast period, please refer to the latest forecasts
