The Weather Man Podcast, I talk about weather!

Heat wave focus shifts from the Mid-Atlantic to portions of the
Southeast/Southern Plains by Monday...
...There's a Slight Risk of Severe Thunderstorms over portions of the
Northern High Plains...
...Severe storms for portions of the Upper Midwest on Monday...
...Monsoon-like conditions persist for the Southwest...
A broad and well entrenched upper ridge centered over the Southern High
Plains/Southwest will eject shortwave energy across the northern tier
states through the early work week. A low pressure system will slide
across the Northeast and potentially into the Canadian maritimes tonight.
Scattered to isolated showers and thunderstorms will focus around an
attendant cold front propagating through much of the Northeast and
northern Mid-Atlantic coast. Remnant moisture from Tropical Cyclone
Alberto, will bring early monsoon-like conditions to the Southwest and
Four Corners region over the next few days. Scattered to isolated showers
and thunderstorms will occur with some instances of flash flooding
possible, particularly over slot canyons and favorable terrain. There's a
Slight Risk (at least 15%) of Excessive Rainfall leading to Flash Flooding
over portions of southeastern Arizona on Monday with Marginal Risks (at
least 5%) persisting through mid-week.
Elsewhere, shortwave energy propagating across southern-central Canada and
the northern tier CONUS will influence more thunderstorm activity over the
Upper Midwest/Great Lakes beginning Monday afternoon. There's a Slight
Risk of Severe Thunderstorms (level 2/5) over parts of the Upper Midwest
late Monday afternoon. Severe/destructive wind gusts are possible for
parts of Minnesota into Wisconsin. A cold front at the surface will act as
a focus for showers and thunderstorms across portions of the Middle
Mississippi Valley and Midwest on Tuesday. There's a Slight Risk of Severe
Thunderstorms for parts of Iowa/northern Missouri into northern Illinois,
southern Wisconsin, southwest Lower Michigan, northern Indiana and
northwestern Ohio. There's potential for an MCS to move across parts of
Wisconsin/Michigan into northern Illinois/Indiana Tuesday morning, the
outflows of which should set the stage for afternoon evening convection to
take place after diurnal heating occurs. There's also a targeted Slight
Risk of Excessive Rainfall over parts of eastern Iowa, southern Wisconsin
and northern Illinois, where storms yielding high rain rates could cause
flash flooding.
A mid-level trough moving off into the Atlantic will promote widespread
record warm low temperatures across the Northeast/Mid-Atlantic Coast
tonight. Lows in the 70s will be of particular concern to those without
adequate cooling or hydration. Heat Advisories are in effect for much of
the aforementioned areas. Upper ridging centered over the Southern High
Plains will produce warmer than average temperatures across the West and
Central U.S. this week. Troughing over the northern tier will keep
temperatures at or below average for parts of the Upper Midwest/Great
Lakes.
