Weather Monday June 10 2024 New York City perfect weather , Dry in the Northeast and West coast

Thunderstorms to be most active across the High Plains into portions of
the Lower Mississippi Valley into parts of the Southeast...
...Hot weather to begin returning to parts of the West early this week...
The same cold front that was associated with severe thunderstorms and
areas of flash flooding from eastern Colorado into southern Missouri on
Saturday will continue to slowly move south through Monday night before
stalling near the Gulf Coast. Low level convergence near the front and a
region of anomalous moisture extending from the Southeast into the
southern Plains and northward into the northern High Plains will help
support numerous showers and thunderstorms over the next couple of days. A
few of the storms will be capable of becoming severe and/or producing
flash flooding as highlighted by Marginal and Slight Risks of severe
thunderstorms and Excessive Rainfall generated by the Storm Prediction
Center and Weather Prediction Center. Temperatures will be pleasantly cool
north of the front, with high temperature departures expected to be 10-20
degrees below average across the southern High Plains and Great Lakes
region on Monday. Temperatures will moderate on Tuesday but remain below
average from Texas/Oklahoma into the middle Mississippi Valley, Northeast
and Mid-Atlantic region. Cloud cover from scattered showers and embedded
thunderstorms will help to keep temperatures down for parts of the Great
Lakes and Northeast today, but a drier trend is likely through Tuesday for
these areas.
An upper level trough across the western U.S. will be preceded by a weak
cold front at the surface which will move eastward through Tuesday. Severe
thunderstorms will be possible from eastern Wyoming into adjacent portions
of South Dakota and western Nebraska on Monday as the cold front moves
into the Great Plains. The cold front will not make much southern progress
across the western U.S. however, and a shift toward zonal flow in the
mid-levels of the atmosphere will be accompanied by warming temperatures
through mid-week for the West. High temperatures are expected to reach
dangerously hot levels for portions of the Sacramento and San Joaquin
Valley in California as well as southern Nevada into southern Arizona.
Excessive Heat Watches have been posted for these regions in anticipation
of the expanding heat early this week with forecast departures ranging
from 10 to 20 degrees above average on Tuesday.
