DISCUSSION. (Today through Monday) Issued at 335 AM CDT Tue May 11 2021
Summary: High pressure over the region will keep things warm and dry over the next several days. Precipitation chances will slowly increase towards the end of the week and into the weekend.
A surface high pressure has set up shop over the Northland and will bring warm and dry conditions through the early parts of the forecast. Surface warming will lead to diurnally driven cumulus clouds populating during the daylight hours and dispersing after sunset for the next several days. Today marks the start of our warming trend thanks to an upper level low moving east away from the Northland and ridging pushing in from the west. Highs today will approach 60 with the rest of the week expected to see highs in the mid to upper 60s. Cooler temperatures will still permeate from Lake Superior keeping the shorelines in the 50s.
The surface high pressure begins to slide off to the southeast Thursday and return flow on the backside of this feature will promote southerly winds back into the Northland. The added moisture from these winds combined with diurnal heating could generate some afternoon rain showers on Thursday and Friday. There still remains some question as to whether or not a mid level shortwave will move over the region during this time span which would further increase the chances for precipitation.
Precipitation chances for this weekend continue to be a challenge. The 00Z suite of model guidance still shows a large divergence in solutions. A low pressure system is forecasted to eject out of the Rockies and traverse across the Midwest bringing widespread rainfall. A low level jet is also expected to ramp up and could elongate the precipitation field into the Northland. But confidence is still not very high in this scenario yet. For now, we have left the mention of "chance" for rainfall this weekend with Sunday being slightly more favorable.
AVIATION. (For the 06Z TAFS through 06Z Tuesday night) Issued at 1229 AM CDT Tue May 11 2021
VFR conditions throughout the forecast period. Surface high pressure will reign supreme over the Northland today with light winds expected. Look for diurnally driven cumulus field to scour the region as the surface warms and then vacate the area after sunset.
MARINE. Issued at 335 AM CDT Tue May 11 2021
A surface high pressure is setting up over the Northland and providing light winds across the Lake. Winds are expected to be less than 10 kts and primarily out of the west today. Waves will remain at 2 feet or less. No hazardous weather is expected over the next 48 hours.
