.OUTLOOK FOR SUNDAY APRIL 20 THROUGH SATURDAY APRIL 26...

At this time, the latest ensemble guidance shows that there will
likely be transitioning from troughing over the region to a
longwave ridge building back in which will translate to overall
cooler temperatures beginning to warm back up with mostly dry
conditions prevailing throughout the entire duration of this
period in the forecast. Please check back for an update, as this
forecast is subject to change.
