Marcus’ 4 a.m. Monday forecast INDIANAPOLIS (WISH) — High pressure is building a “Big Bubble” over Indiana, and it’s parking itself here through the weekend. That means six straight days of sunshine and pleasant temperatures. TODAY: Plenty of sunshine with highs in the mid to upper 60s. Light northwest winds at 5 to 10 mph. TONIGHT: Clear skies and light winds will let temperatures drop fast. Lows in the low to mid 40s for Indianapolis. FROST WATCH for northeast areas: If you’re in these areas, cover sensitive plants before sunset – this would be mainly in low lying areas, and well protected from any breeze. Most areas will likely stay in the lower 40s. TUESDAY: Sunny and warmer. Highs in the upper 60s to near 70 degrees. Morning frost threat ends by 8 a.m. for northeast counties. WEDNESDAY – FRIDAY: Dry pattern continues with temperatures climbing into the low 70s each afternoon. Morning lows in the mid to upper 40s. FIRE WEATHER CONCERNS: Tuesday through Friday will feature increasingly dangerous conditions for outdoor burning: Relative humidity dropping to 30 percent (or lower) each afternoon Light northwest winds 10-15 mph providing oxygen for any fire starts Bone-dry vegetation from the extended dry spell Bottom line: Avoid outdoor burning this week. THE WEEKEND: High pressure holds through Saturday with continued dry weather. Highs in the upper 60s to low 70s. A pattern shift is possible by Sunday or early next week. That could finally bring some rain chances back into the forecast. ...read more read less
