3 satellite sectors moved
Satellite moves MDS STATUS...
Each GOES weather satellite has two “mesoscale sectors” — small, movable windows that the satellite photographs roughly every 60 seconds, far more often than its routine full-disk and continental scans. Forecasters aim them at whatever is most important that day. This section announces where they are being pointed and for how long.
GOES-East is pointing mesoscale sector 1 at a point about 100 mi ESE of Louisville, KY — to support severe thunderstorm and tornado forecasting. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.

GOES-East is pointing mesoscale sector 2 at a point about 40 mi SSE of Omaha, NE — to support severe thunderstorm and tornado forecasting. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.

GOES-West is pointing mesoscale sector 1 at a point about 155 mi WNW of Elko, NV — to support fire weather operations. That means this patch of sky gets a fresh satellite image about once a minute instead of every 5 to 10 minutes, so forecasters can watch storms develop almost in real time.

Critical Weather Day CRITICAL WEATHER DAY STATUS...
NWS does not currently expect to declare a Critical Weather Day in the next three days — no unusual operational precautions are planned.
A “Critical Weather Day” is an internal NWS operations posture. When one is declared, NWS postpones scheduled software, hardware and network changes at the affected offices so that nothing is disturbed while forecasters are working high-impact weather. Emergency changes still get made, but they need senior sign-off. It is a signal about how NWS is protecting its own systems — it is not a forecast or a warning, and it does not tell you anything about conditions where you live.
CWD outlook CRITICAL WEATHER OUTLOOK...
Looking three days ahead, NWS does not expect to need a Critical Weather Day — no system change freezes are anticipated.
