Marine Weather and Tide Forecast for Albert City, IA

UPDATE
Issued at 849 PM CDT Mon Jul 27 2026

Thunderstorms that have developed previously across south central South Dakota heave considerably weakened as more stable air was advected into the storms. Now light rain showers have pushed into locations near and west of the James River. With the stable air in place, think these showers will continue to weaken with southeastward extent. This will leave mostly dry conditions for the overnight hours with maybe a trailing light shower or two persisting through the night. However, low temperatures will remain warm overnight with lows bottoming out in the upper 60s and 70s. This will keep heat indices in the low 70s overnight, continuing warm and humid conditions.

With the influence of a surface high pressure system in place tomorrow, high temperatures will be cooler from what we have seen the past few days with highs warming to the 80s to low 90s. Latest hi-res guidance shows the potential for diurnally driven storms to develop across southwest Minnesota tomorrow afternoon. Despite the influence from the surface high, winds at the surface may be light and variable just enough to create a small convergence zone along the Buffalo Ridge. Forcing looks to remain weak but the right entrance region of an upper level jet will be residing over the forecast area, providing some upper level support. Instability will be sufficient but deep layer shear values will be weaker on the order of 30 knots or so. However, vertical shear values do strengthen higher up in the atmosphere, so if storms are able to develop along this convergence zone, they could be stronger with wind gusts to 50 mph and hail up to dime size. This activity will weaken during the evening hours as the boundary layer stabilizes.

DISCUSSION
Issued at 153 PM CDT Mon Jul 27 2026

Hot and humid conditions improve behind a cold front that passed through the region this morning. Winds behind the front are out of the north and a bit breezy with gusts to around 20 mph. Dewpoints are falling rapidly to the low 60s. However, highs are still expected to climb into the 90s and low 100s, and so Heat Index values will be 100 to 104 degrees F. A Heat Advisory remains in effect for areas along and south of I-90 until 8 pm CDT.

In addition to heat there is a Marginal risk (level 1 of 5) for strong to severe thunderstorms. A shallow wave will pass through the region, triggering storms over western South Dakota late this afternoon into the early evening. These will travel east and begin to impact areas of central South Dakota some time after 9 pm CDT. As storms approach they will be encountering an increasingly stable environment. While severe weather cannot be ruled out, the area most likely to see any stronger storms will be west of the James River.
The main risk with storms will be damaging wind gusts of 65 mph.
Storm intensity will weaken as they continue east becoming scattered rain showers and weak thunderstorms. Rain accumulation will be light, a trace to a hundredth for most of the CWA West of the James River may see up to a tenth of an inch. Showers may linger into the morning commute Tuesday, but impacts should be minimal.

Tuesday surface high pressure settles over central South Dakota turning winds to the southeast. Highs will be cooler, in the 80s east of Highway 81, and in the low 90s to the west. Dew points will climb into the mid 60s to low 70s and will result in muggy conditions once again. However, Heat Index values will remain below critical. Still, it's important to maintain proper hydration and to take breaks out of the heat. Wednesday will be another quiet day with highs in the 90s.

Wednesday night a short wave will work through the upper ridge bringing chances for showers and thunderstorms. There is a very large difference in mid-range guidance on convective parameters, therefore the severity of the storms is uncertain. Thursday isolated to scattered light showers will continue periodically through the day. Thursday afternoon a stronger upper wave moves into the region. This will result in another round of showers and thunderstorms. Mid-range guidance continues to have a wide range of solutions, and severity of storms is once again in question. Over the coming days the trends will be monitored and updates issued as details become clear.

An upper level ridge will push into the region behind the wave for the weekend. Partly cloudy skies and highs in the 80s to low 90s with dry conditions are expected.

One final note: Smoke from wildfires in the western US and Canada is expected to begin to flow into the region today. This will result in milky looking skies and a decrease in air quality. You may even be able to smell smoke at times depending on how deeply we mix each day. With our current upper level pattern smoke is expected to remain in the forecast through at least the middle of the week.
People who are sensitive to air pollutants should use precautions.

AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
Issued at 626 PM CDT Mon Jul 27 2026

VFR conditions begin the TAF period. Showers and thunderstorms have developed across south central South Dakota this evening and will progress eastwards. Good news is that these storms will quickly encounter much more stable air and weaken as they get into the area.
Some showers are possible around KHON but the bulk of the decaying showers and storms will push off to the southeast. Perhaps some very light showers could make it all the way to KSUX but confidence is not high enough to include in a TAF at this time. A few light showers may linger through the night before dry conditions return to the area by tomorrow morning. New showers and thunderstorms may develop tomorrow afternoon but this potential is uncertain. Will continue to monitor this potential.
