Fxus63 kmpx 251034 afdmpx area forecast discussion national weather service twin cities chanhassen mn 534 am cdt Tue jun 25 2019 Updated for 12z TAF discussion below Short term (today through Wednesday) issued at 435 am cdt Tue jun 25 2019 short term concerns remain convective threat over the far northeast cwa this afternoon and threat of convection developing later tonight into Wednesday. Isolated showers finally dissipating across the mn cwa. Patchy mid clouds remains. Should see plenty of sunshine with some cumulus developing. Some hires models develop some widely scattered convection over the northeast CWA later afternoon and ending in the early evening. The short wave over northeast north dakota is forecast to move east and drop over northeast mn this afternoon. Mucapes are forecast to around 500 j kg over the far northeast CWA in the afternoon. Will mention small chance pop over the far northeast for the afternoon early evening. Elsewhere, some cumulus expected with breezy conditions developing into the afternoon, we are expecting temperatures to warm through the upper 70s to lower 80s. Later tonight, we see WAA pattern developing to the southwest. This could develop some scattered thunder into the southwest later tonight. Some hires solutions develop some elevated convection to the southwest and over south dakota later tonight associated with a possible short wave. The href solution moves this possible complex east into western mn Wednesday morning and dieing to the southeast by late morning. The 06z NAM backed off on overall instability into mn but still has the short wave moving in. Will have to carry a small pop into Wednesday morning over the west for the possibility href hrrr arw solution. By late afternoon or early evening the surface warm front will be working into southwest mn and will be the focus for convective development possibly before 00z Thu to the southwest as airmass becomes very unstable. Wednesday high temperatures are expected to warm to the 80 to 85 degree range. Long term (Wednesday night through Monday) issued at 435 am cdt Tue jun 25 2019 the first potential heat wave of the summer and convective trends through Monday continue to be the focus for the long term. The warm front will lift north Wednesday night with potential convection firing as soon as late Wednesday afternoon. The chance will grow Wednesday evening as a LLJ develops over the central plains to eastern nebraska and western iowa. Elevated mixed layer will also advance north with lapse rates exceeding 8 c km across southern mn Wednesday night. In addition, rich low level moisture will reach the CWA during this period, allowing for only a weakly capped atmosphere overnight and MUCAPE exceeding 3000 j kg. Negative factors for thunderstorm development include rising mid level heights and a forcing mechanism aside from the llj. If a remnant MCV or other disturbance can also interact with this environment, there will be a good risk of severe thunderstorms south of i-94. By Thursday, models are in decent agreement in showing a

disturbance riding the crest of the ridge across the upper midwest during the late morning and afternoon. If convection is void Wednesday night, the risk of thunderstorm development will be quite a bit higher Thursday afternoon with this wave moving across. Temperatures may also be cooler than forecast Thursday, should we have a severe MCS move through during peak heating. The ridge builds in aggressively Friday, Saturday, and Sunday with a 595 dm height expected across the central plains Saturday. At this point, it appears the probability is low for convection during this period with disturbances likely remaining well to the north and east. However, the risk is not zero with mesoscale features acting as the main driver for convection in these circumstances. Continued to keep forecast highs and lows close to the nbm, but did raise highs a couple degrees in some places Saturday. 925 mb temps of +26 to +28c on most of the guidance suggests highs in the mid 90s in most places, and possibly upper 90s over west central mn. In addition, ample moisture at the 850 mb level would keep surface dew points from mixing too low, despite the lack of evapotranspiration expected from delayed agriculture growth. Dew points should rise into the lower 70s, which would make for heat indices in the upper 90s to lower 100s Saturday. Lows Friday and Saturday nights should remain in the mid 70s most locations. Excessive heat warnings or heat advisories are appearing likely, especially given the lackluster heat we have had all season. The heat should persist into Sunday and possibly into early next week. There are differences amongst the guidance with how far south a cold front sags during this period. Adding to the temperature uncertainty is convective potential with said front. Aviation (for the 12z tafs through 12z Wednesday morning) issued at 533 am cdt Tue jun 25 2019 vfr through period. May see some widely scattered shra isold tsra over northwest wi this afternoon but should remain north and of of wi TAF sites. Just some cumulus 4-6k ft late morning and becoming mainly skc early tonight with some mid high level clouds moving into the west late. Surface winds becoming w-nw with some gusts to 25kts possible especially over the northeast areas. Then becoming light SW into tonight. Kmsp... No additional concerns.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
