Some rain on the way Wednesday, then clearing skies with a warm Thanksgiving weekend ahead

A quick moving low pressure system will cross southern Manitoba Wednesday bringing an area of rain into the Red River valley by mid to late afternoon into the evening. The bulk of the rain is expected between 4 pm and midnight in Winnipeg and the RRV with general amounts of 5-10 mm expected. Amounts up to 15 mm are possible in some areas where embedded convection will generate locally heavier showers at times. Rain will move out of southern Manitoba overnight Wednesday with clearing skies expected Thursday as a ridge of high pressure builds in from the west. That ridge will cross southern Manitoba Friday bringing sunny skies and seasonable temperatures in the mid teens.

The outlook for Thanksgiving weekend looks fantastic with well above normal temperatures expected. As the ridge moves east of Manitoba, a southwest flow of unseasonably warm air will spread across all of the Prairies Saturday and Sunday, sending temperatures soaring into the 20s along with plenty of sunshine. Temperatures in Winnipeg could be approaching record highs by Sunday (current record high for Sunday Oct 11th is 26.1C on Oct 11 1942) A cold front is forecast to push through southern MB Sunday evening with a chance of showers, followed by  somewhat cooler conditions for holiday Monday (but still above normal with highs of 16-18C) All in all, looks like a great holiday weekend to enjoy fall weather at its finest!

New weather station online!

After 14 years of trusty weather data with an original Davis Vantage Pro weather station, I've finally upgraded to a new Vantage Pro 2 unit.  The new station is equipped with a 24 hr fan aspirated temperature shield which should result in even more accurate temperature readings than before (which were already pretty good).  Wind data will also return, although the anemometer is currently mounted on a 10 foot pole in my backyard surrounded by forest on the north and east sides. As a result, wind speeds and direction will not be ideal, but it's better than nothing. Eventually, I hope to move the anemometer to rooftop level to get more accurate wind readings. The new station will also give UV readings as my old unit did. All the data is uploaded onto my Rob's Obs website and updated every 5 minutes.  Data is also uploaded every 10 minutes to Weather Underground (ID = IMBWINNI3) 

Hopefully, this station gives me just as many years of trusty, reliable and accurate weather data as my original Davis station did.

Rainfall across southern MB overnight

Graphic showing rainfall reports from area of convection last night that tracked across ND/MB border. Bulk of rain fell in northern ND just south of international border where 50-100 mm (2-4") was reported. Generally 15-30 mm fell across far southern MB, with the highest amounts of 20-30 mm in the Pembina valley. Most of the rain fell south of Winnipeg with just a trace to 1 mm reported in the city.

Weather station issues

After 14 years of reliable service, It looks like my trusty Davis Vantage Pro weather station is starting to show its age. I'm experiencing more frequent data transmission problems which means current weather data is not getting uploaded to my website. The issue appears to be a failure with the super-capacitor in the sensor suite (ISS) which helps to power the unit when the solar panel is not operating (nighttime, cloudy skies, weak sun)  As a result, I only get data during bright sunlight hours wen the solar panel is providing power to the unit.  This ISS super-capacitor needs to be replaced (which is a bit of work) or I just might bite the bullet and upgrade to a new weather station altogether (after 14 years, it may be time)  In the meantime, I will try to keep the station running on backup batteries until I figure out what to do with it. If anyone has experience or advice on repairing the super-capacitor on the Davis Vantage Pro ISS, let me know.
