UPDATE.

SHORT TERM. (Today through Monday) Issued at 342 AM CDT Sun Apr 5 2020

Weak ridging aloft accompanied by southerly boundary layer flow will facilitate warmer than normal temperatures through the start of the week. Most areas will see a fair amount of sunshine today, with the exception of locations north of Interstate 94, where mid-level clouds will be on the increase during the afternoon as showers develop to the north due to increasing warm air advection.

Highs today will reach the low to mid 50s in most locations, with increasing clouds tonight holding lows above freezing. Even warmer temperatures are expected on Monday as 925-850mb temps moderate to between +8C and +10C. Expect highs in the mid 50s to mid 60s. While a few spotty showers are possible on Monday, most areas should remain dry until Monday night or Tuesday when the surface trough moves into the area.

LONG TERM. (Monday night through Saturday) Issued at 342 AM CDT Sun Apr 5 2020

The long term period starts out with a surface trough centered across the forecast area on Monday night, with strengthening warm/moist air advection looking to spawn convection from central MN into northern WI as the low level jet increases. Areas along/north of Interstate 94 and east of Interstate 35 still look to have the highest potential for showers and thunderstorms overnight Monday and Tuesday. Given rather steep lapse rates and MUCAPES circa 1000 J/KG on Monday night into Tuesday morning, we should see elevated thunderstorms. By peak heating Tuesday afternoon, the front and warm sector look to have shifted well east/southeast, so any severe threat looks to be out of the area. Despite the morning cold frontal passage, 925-850mb temps still look to be holding up in the +8C to +10C range on Tuesday afternoon, with a brisk westerly component to the winds and clearing skies. Therefore still have confidence that highs in the 60s are achievable.

On Wednesday, the true cold front sweeps across the area, signaling a transition to below-normal temperatures for the remainder of the week. With a strong shortwave trough driving this transition, we could see a few showers on Wednesday as cyclonic flow persists, but after that we look to remain dry through at least Friday.

Notable differences in the large scale pattern arise between the models regarding how northern and southern streams phase next weekend, so confidence is low with respect to the chance of precipitation.

AVIATION. (For the 18Z TAFS through 18Z Monday afternoon) Issued at 1240 PM CDT Sun Apr 5 2020

For all terminals, winds will be generally from the south- southeast for the entire period but decreasing in speed after this afternoon. High level clouds will build in late this evening from west to east. Cigs will drop significantly tomorrow morning as broken to overcast skies are expected on Monday. MVFR to even IFR cigs are looking likely (especially across western Minnesota) as low-level moisture is advected into the region.

KMSP . Winds will be generally out of the south-southeast with a maximum in speed occurring Sunday afternoon. Clouds will move in overnight and generally lower throughout the morning hours resulting in MVFR cigs by later Monday morning. There is a possibility of showers in the vicinity of MSP after 16z so decided to give them a mention.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
