Isolated severe storms cannot be ruled out late this afternoon into this evening across north central minnesota. A ridge will slide eastward from the upper mississippi river valley early this morning into the central great lakes this afternoon. This will keep skies relatively clear through much of the morning and into the early afternoon. Any fog that developed early this morning will dissipate as the mixed layer grows and winds pick up. A trough will dig from southern alberta into the northern plains today. This will slide a cold front across the eastern dakotas into minnesota, which will bring increasing cloud cover this afternoon and evening. In addition, there will be increasing chances of showers and thunderstorms. The pressure gradient will tighten over the region and this will bring gusty southwest winds. Deterministic models continue to slow down the progression of precipitation. This is reflected in the latest forecast with a slower onset of precipitation in comparison to previous forecasts. Expect around 1000-2000 j kg of CAPE late this afternoon into early this evening. Behind the front is where the 40+ knot deep layer shear resides, which is decoupled from the instability. However, it does look like there may be a few hour period where the two line up and this could bring isolated severe storms over north central minnesota. This matches up well with the latest spc day 1 outlook. Main threats with any stronger storms would be large hail and damaging wind gusts. Expect milder readings today in comparison to yesterday due to strong southwesterly warm air advection ahead of the incoming front. Highs range from the upper 70s to the mid 80s. The cold front will slide through the region overnight into early Sunday. This will bring widespread showers and thunderstorms. Am not as concerned about flooding at this point in time due to the progressive nature of the front, but if storms train over the same area then a few spots could see some flooding. Showers and thunderstorms should end across much of the northland by Sunday morning. Behind the front high pressure will build in from the northern plains as a ridge axis moves in. Aloft winds will become northwesterly, which will advect cooler air into the region. This will bring cooler temperatures with highs ranging from the low to mid 70s on Sunday. Expect gusty winds to develop mid to late in the morning and persist through the afternoon due to the mixed layer tapping into the stronger winds aloft behind the departing cold front. Long term (Sunday night through Friday) issued at 356 am cdt Sat aug 17 2019 the extended will start out with high pressure moving over the northland Sunday night into Monday in the wake of the low cold front. Highs Monday will be in the upper seventies to around eighty. |
The models agree another cold front will move into the area Monday night, continuing east of the area by Tuesday evening. Most of the upper support remains north of the international border. There will be enough forcing along the front for a chance for showers and thunderstorms Monday night into Tuesday. Highs Tuesday will be in the seventies. Cooler temperatures will start to move in later Tuesday and especially Tuesday night behind the front. Wednesday will be dry for most areas with highs in the upper sixties to mid seventies. The upper flow will become more zonal late in the week with the gfs suggesting a stronger shortwave will occur over the west causing the upper flow to become more southwest over the weekend. A weak frontal boundary will be over or just northwest of the northland Friday (depending on the model) with warm air advection occurring Thursday into Friday. There will be a chance for showers and thunderstorms late in the week into the weekend with highs from the mid seventies to around eighty. Aviation (for the 12z tafs through 12z Sunday morning) issued at 634 am cdt Sat aug 17 2019 a cold front stretched from eastern manitoba through eastern north dakota into central south dakota early this morning. Mostly clear skies over the northland overnight and has led to areas of fog and stratus. The fog stratus will lift between 12z and 14z. The front will move slowly east today into tonight with chances for showers and storms moving into the northland later today and especially tonight. A few strong storms are possible, mainly over western portions of the northland. Ceilings will lower tonight to MVFR with possible ifr. Winds are expected to be mainly south southwest today and they will be gusty over northern minnesota. The wind will veer to west to northwest behind the front late tonight into Sunday. Marine Issued at 356 am cdt Sat aug 17 2019 an area of high pressure will move off to the southeast today with winds less than 12 knots for most areas. This will allow the wind direction to be variable at times today into tonight. Today will be dry but a cold front will move into the northland tonight and move through western lake superior on Sunday. There will be a chance for showers and storms along this front tonight into Sunday. The wind will turn westerly behind the front on Sunday and continue into Sunday night with speeds less than 15 knots.

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. |
