Triple-digit heat continues, records in jeopardy through the week

YUMA, Ariz. (KYMA) - Unseasonably hot weather continues to grip southwest Arizona, with temperatures climbing to near-record, and even triple-digit, levels across the region.

According to the National Weather Service in Phoenix, a strong high-pressure system remains locked over the Desert Southwest, driving temperatures roughly 15 to 20 degrees above normal for late March.

In Yuma and surrounding communities, highs are expected to reach the upper 90s again before climbing into the 100 to 103-degree range by Wednesday and Thursday.

Those numbers would put the region right at, or above, daily record highs, continuing an already impressive streak of record-breaking temperatures.

Forecasters say this stretch of heat is being fueled by a strengthening ridge of high pressure over the western United States.

While not as extreme as last week's system, it remains unusually strong for this time of year and is expected to hold steady through the end of the workweek.

Along with the heat, breezy conditions are expected to develop during the afternoons and evenings on Wednesday and Thursday, with wind gusts generally between 15 and 25 miles per hour.

While not considered extreme, those winds combined with dry air, with humidity levels as low as 5 to 10%, could elevate fire weather concerns.

Officials warn the early-season heat can still pose serious risks, especially for those spending extended time outdoors.

The National Weather Service recommends staying hydrated, taking frequent breaks in shaded or air-conditioned areas, and avoiding strenuous activity during peak afternoon hours.

Looking ahead to the weekend, temperatures are expected to remain well above normal, potentially continuing the streak of record highs through Saturday and even into early next week.

However, there are signs of change on the horizon.

Meteorologists say the high-pressure system will begin to shift eastward by the end of the weekend, allowing moisture to move into the region.

That could bring increased cloud cover and even a slight chance of showers or thunderstorms, mainly in higher terrain areas east of Phoenix.

While rain chances for lower desert areas like Yuma remain low for now, the added moisture and cloud cover should help temperatures gradually cool heading into next week.

Until then, the message remains clear: despite the calendar still reading March, conditions across the Desert Southwest will feel much more like the peak of summer.
