NOAA Weather Radio Outage

KHGX Radar.

Scattered showers and storms are forecast today as a plume of tropical moisture moves inland. Expect 60-80% coverage near the coast and 20-40% coverage further inland. Brief episodes of heavy rain may lead to localized flooding, mainly near the coast. High temperatures will be in the low 90s with heat index values near 100.

The work week will begin with enhanced moisture for a 40-60% chance of more afternoon thunderstorms, keeping temperature maximums in the low-to-mid 90s. Any remaining storms will weaken after sunset with light south winds and temperature minimums in the upper 70s overnight.

Warm with lows in the 70s inland and low 80s coast. Cannot rule out some patchy late night fog at more rural locations.

Partly cloudy with some isolated daytime showers and thunderstorms in association with the seabreeze. Highs in the 90s.

Seasonably hot. Daytime highs in the 90s and overnight lows in the 70s to low 80s. Rain chances will be low.

The NOAA Weather Radio (NWR) transmitter that serve the Bay City area remains offline. Technicians are aware of this outage. Unfortunately, it will remain out of service until parts arrive.
