Synopsis: A general consensus of models shows mid-level high pressure over the North Pacific and Aleutians, and over the northwestern CONUS. Mid-level low pressure is forecast off the West and East Coasts of the Lower 48 states, with some energy beginning to move onshore in the West. Increased storm activity is expected across much of the southern CONUS during week-2.

Hazards Detailed Summary

For Monday March 30 - Friday April 03: WPC Days 3-7 U.S. Hazards

For Saturday April 04 - Friday April 10: A broad mid-level trough is predicted to be off the Eastern Seaboard at the start of week-2 and drift very slowly eastward (in the mean). This trough is forecast to influence much of the northeastern quadrant of the CONUS for most, if not all, of the period, with cooler temperatures and drier conditions. However, for areas to the south, from the Southern Plains and Lower Mississippi Valley across the remainder of the Gulf Coast region, warmer temperatures and wetter conditions are favored. This is associated with southern stream energy transiting this portion of the country. A slight risk of heavy precipitation is posted for eastern Texas, Louisiana, and adjacent parts of Arkansas and Oklahoma, Apr 4-10, where about 1.5-2.0 inches of rain is expected to fall, in the form of occasional showers and thunderstorms. Localized thunderstorm activity could result in higher precipitation totals.

Widespread cold surface high pressure forecast over Canada is expected to result in the transport of anomalously cold air southward across the north-central states during the first two days of the week-2 period. There is at least a 20% chance that minimum surface temperatures during this time could fall to the 15th percentile or lower. Portions of this region are expected to see minimum temperatures fall below 20 degrees F. Any impacts are likely to be mitigated across the northern Plains, as it is still prior to the growing season in that area.
