COLD BLAST ARRIVES ON MONDAY
October's temperatures, thus far, is trending below normal. Warm days have been few and far between. We did reach 69° on Sunday, which was three degrees above normal, but a much colder air mass is overspreading the Great Lakes and Ohio Valley region. A cold front passed Sunday evening that dropped temperatures over 30° to a Monday morning low of 37°. In wake of this frontal passage, temperatures will take a weak diurnal curve for the 48 hour time period of 8:00 AM Monday to 8:00 AM Wednesday. This November-like chill has prompted NWS to issue a Freeze Warning for Monday night into Tuesday and we will likely end our run of 33+ degree temperatures that has extended 181 days (April 20-October 17). This ranks as the 26th longest growing season since 1943.
Though this morning, started off chilly, we saw a mixture of sunshine and clouds and increasing winds. Winds gusts of 25-35 mph will be continue to be possible this afternoon. Temperatures continue to warm from the upper 30s this morning to middle to upper 40s this afternoon. There is a chance the high temperature may fail to reach 50 for the first time since April 18. If so, it will also mark the coldest high for a October 17 in 74 years. (NOTE: The temperature at the start of the calendar day was 48°, assuming we do not reach 48+ again for the afternoon, this will be recorded as our official maximum temperature for today).
INDY TO SEE FIRST SNOW OF THE SEASON?
A low level pressure trough will generature a few lake enhanced snow showers that will get pulled far enough to have some minimal impacts to Central Indiana. Though we are not expecting any accumulation, it could reduce visibility. Since there isn't a lot of moisture being injected, this will not last very long. The best chance will be anytime tonight between 10:00 PM to 5:00 AM. Could see it also mix with rain as well given temps will be hovering in the lower to middle 30s during these few hours. The last time we had measurable snow was on April 18th. If you are traveling overnight Monday into early Tuesday morning, be sure to watch out for some slick spots.

COLD AIR FADES, WARMER AIR INVADE
The cold open to the week will not persist all the way through to the weekend. As high pressure slides in, skies will continue to brighten for Tuesday and Wednesday afternoon and allow slightly warmer temperatures to move in. It won't be much but it will help us just enough to get back towards the 50s. We will get on the backside of high pressure for Thursday and Friday and with a southwesterly air flow, this will aid temperatures in reaching 55+ for highs to wrap up the week. We should reach middle to upper 60s on Friday. By the weekend, a warm front will boost temps back into the 70s for both Saturday and Sunday. Gusty winds will continue to mix in. Partly Cloudy to Mostly Sunny Skies seems feasible each afternoon from Tuesday to Sunday with no additional precipitation.

ABNORMALLY DRY CONDITIONS PERSISTS
We generally don't think of a drought in colder months but so far we have only received 0.02" of rain thus far this month. October 2022 is quickly rising in the ranks to the top as one of the most driest for the first 17 days for any month of October on record. 5th driest since 1943. This dry pattern goes a little farther back to the last week of September. This is the 4th driest September 25 - October 17 in 65 years. Drier periods of weather can periodically lead to elevated fire danger when coupled with low relative humidity and increased winds. Keep close eye on the forecast in the days ahead for future "Red Flag Warning" headlines.
