Rain in the forecast for parched Alberta fields



Much needed rain is in the forecast for south and central Alberta this week, and southern Manitoba will likely receive a significant amount of precipitation early next week.

This map, from the U.S. National Weather Service Weather Prediction Center, was issued just before noon May 17 and it’s for 6 p.m. Thursday to 6 p.m. Friday.

A low pressure system is moving east out of the mountains across south and central Alberta.


Here is the precipitation forecast for 6 p.m. Friday to 6 p.m. Saturday.

Instead of moving south and along the U.S. and Canadian border, which the weather models predicted yesterday, the system looks like it will move into central Alberta.



The system looks like it could touch areas that have received very little rain recently.

Below is the accumulated precipitation forecast by Environment Canada for April 1 to May 16.

The dark red areas on the map have received less than 25 mm of rain since April 1 but a large part of this parched area, from Calgary to Meadow Lake, Saskatchewan, could benefit from the approaching weather system.


The wildfire risk remains high or extreme across much of the Prairies.

The recent rains brought some relief, however even areas that received significant rainfall are again under an extreme fire warning as this map, issued on May 17 from Natural Resources Canada, shows.




This 48 hour rain accumulation map, for 6 p.m. Saturday May 21 to 6 p.m. Monday shows, much of the prairie growing regions has a slightly greater than average chance of taking on some rain.


Then starting Monday afternoon a low pressure system could develop over southern Manitoba and bring a significant amount of rain in the following 48 hours.



Looking ahead to following week, May 24 to May 30, the system that may bring rain to southern Manitoba looks like it could settle in and bring more precipitation to southern Manitoba.


The following maps are precipitation forecasts from the U.S. Environmental Modeling Center at NCEP.

From May 31 to June 6 northern Saskatchewan could be in for more rain, and the June 7 to June 13 map shows the southern Prairies could get some precipitation.wk3wk4
