Weather Underground midday recap for Sunday, July 28, 2013.
Areas of active weather continued across the East on Sunday, while
showers and thunderstorms over the Rockies advanced eastward into the
Plains.
In the East, a strong low pressure system located over the Great Lakes
lifted into Ontario and pushed a cold front eastward across the
Appalachians toward the East Coast. As the northern portion of this cold
front advanced eastward, the southern portion of this disturbances
reached across the Southeast. Showers and thunderstorms developed ahead
of the cold front from the Northeast through the Mid-Atlantic states and
into the northern shores of the Gulf of Mexico. Flood Advisories and
Flood Warnings were issued in areas of the Mid-Atlantic and the
Southeast due to periods of heavy rainfall. Meanwhile, wet weather
continued in the Upper Great Lakes-primarily in eastern Wisconsin and
the Upper Peninsula of Michigan-due to the proximity of the departing
low.
Out West, monsoonal moisture over the Southwest maintained showers and
thunderstorms from the high elevations of California through the Four
Corners. Flooding remained possible with these storms across the desert
locations. Just ahead of this activity, a trough of low pressure
advanced off the Central Rockies and into the Central and Southern
Plains and supported showers and potentially strong thunderstorms from
northern Texas through the Northern High Plains.
