Active & Strong NW then W/SW later next week - wind/rain/snow potential

MSLP Anomaly show anomalies for pressure anomalies for the rest of the month

A brief and Early Outlook
It’s still early days, but current models continue to point towards an active spell of weather as August wraps up and September begins. A strong northwesterly flow looks likely to set in later this month, bringing heavy rain to the West Coast and strong to gale-force winds out east.

❄️ Looking Ahead
Further out, and with the reminder that forecasts this far ahead can change with each new model run, the latest guidance suggests a shift to a west to southwest flow in early September. This could bring the risk of snowfall across parts of the country. Whether this turns into a low-level snow event or remains confined to high-country and hilltop areas should become clearer in the coming days.
