FORECASTER: Hilary Smith SYNOPTIC OVERVIEW A high pressure system has moved out of the SPADE region into central AB. There is low pressure located at the borders of YK/NWT/BC with a trough going down into central Idaho. According to ECCC weather briefings, conditions will be unsettled tomorrow which could lead to showers or thunderstorms, which is reinforced by the upper low moving west across BC. An isolated severe storm that could bring 2-3 cm hail is predicted in the south-central foothills.

FORECASTER: Selina Mitchell SYNOPTIC OVERVIEW: A surface high is located on the coast off BC. A low pressure system is forecasted to move along the foothills of the mountains and by Tuesday is forecasted to be to the east of the SPADE region. By Wednesday as the low tracks further south, we expect more upslope precipitation along the foothills of the Rockies, bringing precipitation to the eastern side of our region. GEM global shows the low deepening throughout the week.
Forecaster : Cécile Carton SYNOPTIC OVERVIEW An upper trough and an associated cold front begin to move towards BC, and will probably bring showers and thunderstorms in BC for Sunday afternoon. These conditions will supposedly continue into Monday and Tuesday. Stabilized conditions are expected in Alberta tomorrow as the upper ridge of high pressure which was located in BC today is moving eastwards.
FORECASTER: Hilary Smith SYNOPTIC OVERVIEW There is currently high pressure located over the Rockies. The low pressure that was affecting the area has moved eastward to the border of AB and SK. According to ECCC weather briefings, a high pressure ridge is building on the BC coast which will bring clear and dry conditions to the interior of BC tomorrow and move eastward towards AB over the course of the day.
FORECASTER: Aurélie Desroches-Lapointe SYNOPTIC OVERVIEW: The cyclonic circulation around a surface low pressure system surported by a 500hPa trought is currently located over the Northern border between Alberta and Manitoba. The associate driven northwesterly flow may bring precipitation over our study area. Due to the orogrpahy and the warm expected temperatures, intermittent rain episodes are forecasted for today for the eastern side of the divide. A major low pressure system is currently in the Pacific Ocean. There is currently a ridge between our study area and this system, specifically on the west coast of British Columbia. The long-term models suggest an eastward shift of this synoptic pattern, causing our study area to be affected by this depression over the next week. A follow-up of the short-term models will make it possible to bring more precision on the precipitation events that are expected, considering that snow could occure.
FORECASTER: Hilary Smith SYNOPTIC OVERVIEW There is a low pressure system located over the BC interior and moving into Alberta, as well as a cold front moving into the SPADE region from the NW. According to ECCC weather briefings, there will be unsettled conditions after the passage of the cold front through the region. With the cold front moving in AB, there is a chance for thunderstorms tomorrow afternoon. There is also still a chance of thunderstorms in the BC interior.
FORECASTER: Jeremy Morris SYNOPTIC OVERVIEW The cold front is making its way across the province today, sweeping its way southeastwards across the southern interior causing cold temperatures and isolated showers with a risk of wind gusts and small hail. Wet conditions may continue through tomorrow while instability remains. Within the SPADE region, this translates to predictions of regional precipitation, however the available high resolution models (GEM2.5 and HRR) do not predict significant rain, suggesting that possible events will be site specific as a function of the convective nature of cold front precipitation.
FORECASTER: Hilary Smith SYNOPTIC OVERVIEW There is currently a high pressure system located directly over the Rockies. Tomorrow a cold front will be moving across the BC interior and into western Alberta, which will bring cooler temperatures and the possibility of severe thunderstorms on both sides of the continental divide. According to ECCC weather briefings, the high pressure ridge will likely rebuild in BC on Friday.
Forecaster : Cécile Carton SYNOPTIC OVERVIEW A cold front will begin to sweep south across the BC interior today, provoking showers and risk of thunderstorms. These showers and thunderstorms will persist through the night and spread eastward. On Thursday, as the front continues to move across BC, the atmosphere will be destabilized. Temperatures will be several degrees cooler. Showers and thunderstorms over BC interior will spread to the southern interior of BC on Thursday afternoon. But by Friday this feature will already be moving into Alberta, leaving a ridge of high pressure to rebuild over BC. This will mean clearing from west to east through the day.
FORECASTER(S): Selina Mitchell & Juris Almonte SYNOPTIC OVERVIEW: Much like yesterday's forecast, upper level ridging (700 and upwards) is building over BC, bringing a north westerly flow over the SPADE region, therefore some cooler temperatures aloft. Convective cells may pop up, but is more likely to the north of our region. Satellite imagery shows cloud cover over our area. Tomorrow should bring warmer temperatures.
