SYNOPSIS AND OUTLOOK:
Cloudy to partly cloudy skies and warm temperatures will continue today. An unstable atmosphere may bring us a slight chance of showers or thunderstorms later today. Rain chances will increase tomorrow as an upper-level low pressure trough over Arizona moves east and a cold front begins to slip south into Texas.
This morning, a semi-stationary cold front extends from lows in New Mexico and southeast Colorado across the Texas Panhandle and on east through the Mid-South to a low in the Atlantic. A second cold front stretches from the Pacific and Southern California through Nevada to lows in Utah and Wyoming. A third cold front is moving south into Montana and North Dakota. Elsewhere, high pressure sits over Oregon and a surface trough and low lingers over Mexico.
At the upper-levels we a slightly more zonal west to east flow with an upper-level low in the Atlantic south of Nova Scotia, a high pressure ridge over the northern Plains and a developing upper-level low and trough is found over the western third of the country.
Fairly stable conditions today should give way to increasing rain chances again by Monday as the upper-level trough to our west moves east and a cold front begins moving south into Texas. After a wet start to the week, clearing skies, cooler temperatures and lower humidity levels will bring near ideal spring conditions for the middle of the week.
The Tropical Atlantic Basin remains quiet overall with no active tropical cyclones and tropical development not expected over the coming 48-hours.
