A ridge of high pressure is building over B.C. this week and appears to be strengthening into early next week. It will bring an extended period of hot and dry weather.
• The areas most likely to reach Heat Warning criteria are the Central and Southwestern Interior, South Coast, and inland sections of the North and Central Coasts.
• There is a chance of marginally reaching criteria this week; however, a greater likelihood early next week. It is yet uncertain how high temperatures may climb next week.
• Generally, daytime high temperatures are expected to reach the mid to high 30s in the Southwestern Interior, and high 20s or low 30s along parts of the Coast and Central Interior.
• Overnight lows are expected to be in the mid to high teens.
• It is yet unclear how long the heat may persist.
• Several weather models indicate a weak upper level disturbance moving through Washington State on Friday (July 22) which could limit temperatures for southern B.C. and may produce thunderstorms and associated lightning.
