4/30 – Rob’s “Warmer & Humid” Tuesday Morning Forecast

0

At the surface, the Bermuda high is in place with an axis westward along much of the Gulf Coast. Locally we are seeing weak onshore flow with some low stratus and PATCHY FOG moving from the Gulf.

An upper impulse over Arizona will weaken as it gets picked up by a stronger northern stream system currently off the Pacific Northwest coast over the next 72 hours. This will keep the main surface low track well to our northwest. Cannot totally rule out some isolated convection breaking out over the next few days, primarily in northwest portions of our region, but widespread organized activity is not anticipated through Thursday. Low temperatures will be well above normal, with highs 3-5 degrees above normal.

Impulses moving across the boundaries to our north will begin to elevate the potential for showers and t-storms this weekend with Saturday carrying the best chances. If there’s a day that will be somewhat more favored to be dry, it would be Sunday.
