Weather forecast – 14 UTC 16 May 2019

FORECASTER: Stephen Déry

SYNOPTIC OVERVIEW: A low pressure developing in the central interior of BC is advecting moisture northward towards the continental divide with associated precipitation. This initial round of moisture advection will abate with drier air filtering in from the Pacific Northwest of the United States before a second round of moisture affects the area. This southerly flow of air is associated with a deep upper level trough and associated low level cyclone off the coast of northern California. This pattern will progress slowly eastward while continuing to push moisture into the Canadian Rockies into the weekend.

​Fortress 
Conditions will remain cool at Fortress Mountain today and will hover just above the freezing mark today in cloudy, rainy skies. Some light to moderate precipitation (~5 mm) is possible during the remainder of the day, tonight and tomorrow. Freezing level will stay near 2000 m throughout the day, suggesting possible rain/snow mix at Fortress today.

​Nipika
Cloudy conditions with a chance of showers today. Temperatures will remain on the mild side and likely reach 11°C by the afternoon. This pattern will persist overnight before steady rain affects the area again overnight (starting around 10 pm) and on Friday.
